+
+ -b
+ Read in binary mode when computing hashes.
+
+ -c
+ Verify the the files listed in file against the
+ checksums listed on the same lines. The file
+ shall be formatted as the output of the utility
+ when this option is not used. See the STDOUT
+ section for more information. If a file is listed
+ multiple times, it need only match one of the
+ checksums listed for the file.
+
+ The length of the listed checksums need not match
+ the length output by this utility; before the
+ checksums are compared, they are truncated to the
+ shorter of the two checksums.
+
+ -t
+ Read in text mode when computing hashes.
+
+ -W options
+ Comma-sepearated list of implementation-specific
+ options. The following options are supported:
+

+ format shall be "lowercase" if the checksums
+ shall be printed in lowercase hexadecimal
+ format (default), "uppercase" for uppercase
+ hexadecimal format, or "binary" for binary
+ format without anything but the checksum
+ printed to standard output. This option is
+ ignored if the -c option is used.
+
+ input=format
+ format shall be "binary" if the files are
+ be read in binary mode, "text" if the files
+ shall be read in text mode, or "hexadecimal"
+ they shall be decoded from hexadecimal to
+ binary. If the -c option is used, the mode
+ specification associated with a file is
+ overrides this behaviour for that file if
+ the line specifies hexadecimal mode.
+
+ threads=count
+ The maximum number of threads that the
+ utility may use. If "auto" is specified,
+ the utility selects a default value, which
+ currently is the number of online CPU threads
+ (at any time; assumed to be 8 if it cannot
+ be determined) minus 2, or 1 if this would
+ be less than 1.
+
+ recursive
+ If a file operand is a directory, the checksum
+ is computed for all files recursively.
+ This option is ignored if the -c option is
+ used.
+
+ no-recursive
+ The utility shall traverse directories.
+ (This is the default behaviour).
+
+ -w
+ Warn about, but skip, lines that are not properly
+ formatted.
+
+ -z
+ Use NUL byte as line ending instead of LF.
+
+ There is no difference between binary mode and text mode,
+ so the -b and -t options are ignored.
+
+OPERANDS
+ The following operand is supported:
+
+ file
+ The file to read and compute the checksum for, or if
+ the -c option is used, use as the listing of files
+ and checksums to verify the files against. If dash
+ ('-') is used or if no file operand is specified,
+ standard input will be used.
+
+STDOUT
+ If the -c option is not used, the utility shall print the
+ following line for each calculated checksum, however there
+ are options that modify the format; see the OPTIONS section
+ for more information:
+
+ "%s:%s %c%s\n", <hash function>, <hash>, <mode>,
+ <file>
+
+ where <mode> is SP (' ') for text mode, an asterisk ('*')
+ for binary mode, or a pound sign ('#') for hexadecimal
+ mode; however if there is no difference between binary
+ mode and text mode and either is selected, SP (' ')
+ (text mode) is used.
+
+ If the -c option the output shall be on the format:
+
+ "%s: %s\n", <file>, <validity>
+
+ where <validity> is an implementation specified string
+ that describes whether the checksum was valid (possibly
+ with remarks), the file did not exist, the file could
+ not be read (possibly with error information), or if
+ the checksum was invalid or could not be compared
+ (possibly with remarks). The -z option does not modify
+ the line ending.
+
+EXIT STATUS
+ The following exit values are returned:
+
+ 0 Successful completion.
+
+ 1 Checksums did not match or a file did not exist.
+
+ 2 An error occurred.
+
+NOTES
+ Other implementations do not necessarily recognise the
+ '#' mode specifier in checksum list files.

+.SH DESCRIPTION
+The
+.B b512sum
+utility calculates and prints or checks BLAKE-512
+checksums.
+.PP
+The
+.B b512sum
+utility can also check a file against multiple BLAKE-512
+checksums, and check that the file matches at least one
+of the listed checksums.
+
+.SH OPTIONS
+The b512sum utility conforms to the Base Definitions
+volume of POSIX.1-2017,
+.IR "Section 12.2" ,
+.IR "Utility Syntax Guidelines" .
+.PP
+The following options are supported:
+.TP
+.B -B
+Equivalent to
+.BR "-W output=binary" .
+.TP
+.B -b
+Read in binary mode when computing hashes.
+.TP
+.B -c
+Verify the the files listed in file against the
+checksums listed on the same lines. The file
+shall be formatted as the output of the utility
+when this option is not used. See the
+.B STDOUT
+section for more information. If a file is listed
+multiple times, it need only match one of the
+checksums listed for the file.
+
+The length of the listed checksums need not match
+the length output by this utility; before the
+checksums are compared, they are truncated to the
+shorter of the two checksums.
+.TP
+.B -L
+Equivalent to
+.BR "-W output=lowercase" .
+.TP
+.BR -S \ \fIsalt\fP
+32-byte salt, encoded as a 64 character long
+hexadecimal string.
+.TP
+.B -t
+Read in text mode when computing hashes.
+.TP
+.B -U
+Equivalent to
+.BR "-W output=uppercase" .
+.TP
+.BR -W \ \fIoptions\fP
+Comma-sepearated list of implementation-specific
+options. The following options are supported:
+.RS
+.TP
+.BI output= format
+.I format
+shall be
+.RB \(dq lowercase \(dq
+if the checksums shall be printed in lowercase
+hexadecimal format (default),
+.RB \(dq uppercase \(dq

+.RB \(dq binary \(dq
+if the files are be read in binary mode,
+.RB \(dq text \(dq
+if the files shall be read in text mode, or

+they shall be decoded from hexadecimal to
+binary. If the
+.B -c
+option is used, the mode specification
+associated with a file is overrides this
+behaviour for that file if the line
+specifies hexadecimal mode.
+.TP
+.B recursive
+If a
+.I file
+operand is a directory, the checksum is computed for
+all files recursively. This option is ignored if the
+.B -c
+option is used.
+.TP
+.B no-recursive
+The utility shall traverse directories.
+(This is the default behaviour).
+.RE
+.TP
+.B -w
+Warn about, but skip, lines that are not properly
+formatted.
+.TP
+.B -x
+Equivalent to
+.BR "-W input=hexadeximal" .
+.TP
+.B -z
+Use NUL byte as line ending instead of LF.
+.PP
+There is no difference between binary mode and text mode,

+.TH KECCAK224SUM 1 anysum
+.SH NAME
+keccak224sum - compute or verify against multiple Keccak-224 hashes
+
+.SH SYNOPSIS
+.B keccak224sum
+.RB [ -c
+.RB [ -w ]]
+.RB [ -W
+.IR options ]\ ...
+.RB [ -z ]
+.RI [ file ]\ ...
+
+.SH DESCRIPTION
+The
+.B keccak224sum
+utility calculates and prints or checks Keccak-224
+(Keccak[r=1152,c=448,n=224]) checksums.
+.PP
+The
+.B keccak224sum
+utility can also check a file against multiple Keccak-224
+checksums, and check that the file matches at least one
+of the listed checksums.
+
+.SH OPTIONS
+The keccak224sum utility conforms to the Base Definitions
+volume of POSIX.1-2017,
+.IR "Section 12.2" ,
+.IR "Utility Syntax Guidelines" .
+.PP
+The following options are supported:
+.TP
+.B -b
+Equivalent to
+.BR "-W output=binary" .
+.TP
+.B -c
+Verify the the files listed in file against the
+checksums listed on the same lines. The file
+shall be formatted as the output of the utility
+when this option is not used. See the
+.B STDOUT
+section for more information. If a file is listed
+multiple times, it need only match one of the
+checksums listed for the file.
+
+The length of the listed checksums need not match
+the length output by this utility; before the
+checksums are compared, they are truncated to the
+shorter of the two checksums.
+.TP
+.B -l
+Equivalent to
+.BR "-W output=lowercase" .
+.TP
+.B -u
+Equivalent to
+.BR "-W output=uppercase" .
+.TP
+.B -v
+Print Keccak parameters to standard error.
+.TP
+.BR -W \ \fIoptions\fP
+Comma-sepearated list of implementation-specific
+options. The following options are supported:
+.RS
+.TP
+.BI output= format
+.I format
+shall be
+.RB \(dq lowercase \(dq
+if the checksums shall be printed in lowercase
+hexadecimal format (default),
+.RB \(dq uppercase \(dq
+for uppercase hexadecimal format, or
+.RB \(dq binary \(dq
+for binary format without anything but the
+checksum printed to standard output. This
+option is ignored if the
+.B -c
+option is used.
+.TP
+.BI input= format
+.I format
+shall be
+.RB \(dq binary \(dq
+if the files are be read in binary mode,
+.RB \(dq text \(dq
+if the files shall be read in text mode, or
+.RB \(dq hexadecimal \(dq
+they shall be decoded from hexadecimal to
+binary. If the
+.B -c
+option is used, the mode specification
+associated with a file is overrides this
+behaviour for that file if the line
+specifies hexadecimal mode.
+.TP
+.B recursive
+If a
+.I file
+operand is a directory, the checksum is computed for
+all files recursively. This option is ignored if the
+.B -c
+option is used.
+.TP
+.B no-recursive
+The utility shall traverse directories.
+(This is the default behaviour).
+.RE
+.TP
+.B -w
+Warn about, but skip, lines that are not properly
+formatted.
+.TP
+.B -x
+Equivalent to
+.BR "-W input=hexadeximal" .
+.TP
+.B -z
+Use NUL byte as line ending instead of LF.
+.PP
+There is no difference between binary mode and text mode.
+
+.SH OPERANDS
+The following operand is supported:
+.TP
+.I file
+The file to read and compute the checksum for, or if the
+.B -c
+option is used, use as the listing of files and checksums
+to verify the files against. If dash
+.RB (' - ')
+is used or if no file operand is specified, standard input
+will be used.
+
+.SH STDOUT
+If the
+.B -c
+option is not used, the utility shall print the following
+line for each calculated checksum, however there are options
+that modify the format; see the
+.B OPTIONS
+section for more information:
+.PP
+.RS
+.B \(dq%s %c%s\en\(dq,
+.RI < hash >\fB,\fP
+.RI < mode >\fB,\fP
+.RI < file >
+.RE
+.PP
+where
+.I mode
+is SP (' ') for text mode, an asterisk
+.RB (' * ')
+for binary mode, or a pound sign
+.RB (' # ')
+for hexadecimal mode; however if there is no difference
+between binary mode and text mode and either is selected,
+SP (' ') (text mode) is used.
+.PP
+If the
+.B -c
+option the output shall be on the format:
+.PP
+.RS
+.B \(dq%s: %s\en\(dq,
+.RI < file >\fB,\fP
+.RI < validity >
+.RE
+.PP
+where
+.I validity

+The
+.B md2sum
+utility calculates and prints or checks MD2 checksums.
+.PP
+The
+.B md2sum
+utility can also check a file against multiple MD2
+checksums, and check that the file matches at least one
+of the listed checksums.
+
+.SH OPTIONS
+The md2sum utility conforms to the Base Definitions volume of
+POSIX.1-2017,
+.IR "Section 12.2" ,
+.IR "Utility Syntax Guidelines" .
+.PP
+The following options are supported:
+.TP
+.B -b
+Read in binary mode when computing hashes.
+.TP
+.B -c
+Verify the the files listed in file against the
+checksums listed on the same lines. The file
+shall be formatted as the output of the utility
+when this option is not used. See the
+.B STDOUT
+section for more information. If a file is listed
+multiple times, it need only match one of the
+checksums listed for the file.
+
+The length of the listed checksums need not match
+the length output by this utility; before the
+checksums are compared, they are truncated to the
+shorter of the two checksums.
