Line 42:

Some encodings (the original version of BinHex and the recommended encoding for [[CipherSaber]]) use four bits instead of six, mapping all possible sequences of 4 bits onto the 16 standard [[hexadecimal]] digits.

Using 4 bits per encoded character leads to a 50% longer output than base64, but simplifies encoding and decoding -- expanding each byte in the source independently to two encoded bytes is simpler than base64's expanding 3 source bytes to 4 encoded bytes.
