Enumerations
BASE64
Original PEM base64-encoding: 6 bits (0..63) enocded as one ASCII character: 0..23 = 'A'..'Z', 24..51 = 'a'..'z', 52..61 = '0'..'9', 62 = '+', 63 = '/', '=' = pad byte. Four bytes encoded as three characters. CR/LF every 64 characters.
BASE64URL
URL and Filename safe base64-encoding: same as BASE64 except 62 = '-', 63 = '_' and no CR/LFs. Pad byte? Can be used in URLs without requiring escaping.
HEX
Hexadecmimal: For input, accepts HEX_UPPER, HEX_LOWER, and HEX_COLONS format. For output, produces HEX_LOWER format.
HEX_COLONS
Hexadecimal with 0..9 = '0'..'9' and 10..15 = 'A'..'F'; ':' between each hex byte. Matches BLOB_TO_HEX() output format.
HEX_LOWER
Hexadecimal with 0..9 = '0'..'9' and 10..15 = 'a'..'f'.
HEX_UPPER
Hexadecimal with 0..9 = '0'..'9' and 10..15 = 'A'..'F'.
NONE
No encoding: input or output text is raw binary.
