Otherwise -it will return one of the following constants. -.PP -.TP -.B LIBKECCAK_SPEC_ERROR_BITRATE_NONPOSITIVE -The specified bitrate was non-positive. -.TP -.B LIBKECCAK_SPEC_ERROR_BITRATE_MOD_8 -The specified bitrate was not equivalent to 0 -modulus 8, that is, it was not in whole bytes. -.TP -.B LIBKECCAK_SPEC_ERROR_CAPACITY_NONPOSITIVE -The specified capacity was non-positive. -.TP -.B LIBKECCAK_SPEC_ERROR_CAPACITY_MOD_8 -The specified capacity was not equivalent to 0 -modulus 8, that is, it was not in whole bytes. -.TP -.B LIBKECCAK_SPEC_ERROR_OUTPUT_NONPOSITIVE -The specified output size was non-positive. -.TP -.B LIBKECCAK_SPEC_ERROR_STATE_TOO_LARGE -The state size, that is the sum of the bitrate -and the capacity, exceeded the supported limit -(currently at 1600 bits.) -.TP -.B LIBKECCAK_SPEC_ERROR_STATE_MOD_25 -The state size, that is the sum of the bitrate -and the capacity, in bits, was not equivalent -to 0 modulus 25.
