Turns ASCII base-16 hexadecimal byte string into binary string,
case-insensitively. Non-hex characters may not appear in string.
DecodeBase32(ascii:str[, alphabet:str]) → binary:str
Turns ASCII into binary using provided alphabet. The default
decoding uses Crockford's base32 alphabet in a permissive way
that ignores whitespaces and dash ('-') and stops at the first
character outside of the alphabet.
EncodeBase32(binary:str[, alphabet:str]) → ascii:str
Turns binary into ASCII using provided alphabet (using Crockford's
base32 encoding by default). Any alphabet that has a power of 2
length (up to 128) may be supplied for encoding and decoding,
which allows to provide alternative base32 encodings.
DecodeBase64(ascii:str) → binary:str
Turns ASCII into binary, in a permissive way that ignores
Turns ASCII into binary in a permissive way that ignores
characters outside the base64 alphabet, such as whitespace. See
decodebase64.c.
