func Base64_24Bit ¶
Base64_24Bit is a variant of Base64 encoding, commonly used with password hashing algorithms to encode the result of their checksum output.
The algorithm operates on up to 3 bytes at a time, encoding the following 6-bit sequences into up to 4 hash64 ASCII bytes.
1. Bottom 6 bits of the first byte 2. Top 2 bits of the first byte, and bottom 4 bits of the second byte. 3. Top 4 bits of the second byte, and bottom 2 bits of the third byte. 4. Top 6 bits of the third byte.
This encoding method does not emit padding bytes as Base64 does.
Salt represents a salt.
Generate generates a random salt of a given length.
The length is set thus:
length > SaltLenMax: length = SaltLenMax length < SaltLenMin: length = SaltLenMin
func (*Salt) GenerateWRounds ¶
GenerateWRounds creates a random salt with the random bytes being of the length provided, and the rounds parameter set as specified.
The parameters are set thus:
length > SaltLenMax: length = SaltLenMax length < SaltLenMin: length = SaltLenMin rounds < 0: rounds = RoundsDefault rounds < RoundsMin: rounds = RoundsMin rounds > RoundsMax: rounds = RoundsMax
If rounds is equal to RoundsDefault, then the "rounds=" part of the salt is removed.
