Usage notes

The usage notes for CSNBOWH.

Table 1 summarizes the message digest size and the algorithm block size for each hash method.

Table 1. Usage of hash methods
Usage of hash methods with three columns: hash method, message digest size and algorithm block length
Hash method	Message digest size	Algorithm block size (see Note 1)
MD5	128 bits (16 bytes)	512 bits (64 bytes)
RIPEMD-160	160 bits (20 bytes)	512 bits (64 bytes)
SHA-1	160 bits (20 bytes)	512 bits (64 bytes)
SHA-224	224 bits (28 bytes)	512 bits (64 bytes)
SHA-256	256 bits (32 bytes)	512 bits (64 bytes)
SHA-384	384 bits (48 bytes)	1024 bits (128 bytes)
SHA-512	512 bits (64 bytes)	1024 bits (128 bytes)
SHA3-224	224 bits (28 bytes)	1152 bits (144 bytes)
SHA3-256	256 bits (32 bytes)	1088 bits (136 bytes)
SHA3-384	384 bits (48 bytes)	832 bits (104 bytes)
SHA3-512	512 bits (64 bytes)	576 bits (72 bytes)
Note: If FIRST or MIDDLE calls are made, the text size must be greater than 0 and a multiple of the algorithm block size.

Although the algorithms accept zero bit length text, it is not supported for any hashing method.
