Encode a lazy Text value in Base16 with padding.

See: RFC-4648 section 8

Examples:

>>> encodeBase16 "Sun"
"53756e"

Decode a Base16-encoded lazy Text value.

See: RFC-4648 section 8

Examples:

>>> decodeBase16 "53756e"
Right "Sun"

>>> decodeBase16 "6x"
Left "invalid character at offset: 1"

Attempt to decode a lazy Text value as Base16, converting from ByteString to Text according to some encoding function. In practice, This is something like decodeUtf8', which may produce an error.

See: RFC-4648 section 8

decodeBase16With decodeUtf8'
  :: ByteString -> Either (Base16Error UnicodeException) Text

Since: 0.3.0.0

Decode a Base16-encoded lazy Text value leniently, using a strategy that never fails.

Warning: in the conversion to unicode text, exceptions may be thrown. Please use decodeBase16' if you are unsure if you are working with base16-encoded values, or if you expect garbage.

N.B.: this is not RFC 4648-compliant. It may give you garbage if you're not careful!

Examples:

>>> decodeBase16Lenient "53756e"
"Sun"

>>> decodeBase16Lenient "6x6x"
"f"

Tell whether a lazy Text value is Base16-encoded.

Examples:

>>> isBase16 "666f6"
False

>>> isBase16 "666f"
True

Tell whether a lazy Text value is a valid Base16 format.

This will not tell you whether or not this is a correct Base16 representation, only that it conforms to the correct shape. To check whether it is a true Base16 encoded Text value, use isBase16.

Examples:

>>> isValidBase16 "666f+/6"
False

>>> isValidBase16 "666f6"
True
