Data.ByteString.Base16

Fast and efficient encoding and decoding of base16-encoded strings.

Documentation

encode :: ByteString -> ByteString

Encode a string into base16 form. The result will always be a multiple of 2 bytes in length.

Example:

 encode "foo"  == "666f6f"

decode :: ByteString -> (ByteString, ByteString)

Decode a string from base16 form. The first element of the returned tuple contains the decoded data. The second element starts at the first invalid base16 sequence in the original string.

Examples:

 decode "666f6f"  == ("foo", "")
 decode "66quux"  == ("f", "quux")
 decode "666quux" == ("f", "6quux")
