Text.Hex

Encodes a byte string as hexadecimal number represented in text

Each byte of the input is converted into two characters in the resulting text.

>>> (encodeHex . ByteString.singleton) 192"c0"

>>> (encodeHex . ByteString.singleton) 168"a8"

>>> (encodeHex . ByteString.pack) [192, 168, 1, 2]"c0a80102"

Text produced by encodeHex can be converted back to a ByteString using decodeHex.

The lazy variant of encodeHex is lazilyEncodeHex.

Decodes hexadecimal text as a byte string

The lazy variant of encodeHex

With laziness, it is possible to encode byte strings of infinite length:

>>> (LazyText.take 8 . lazilyEncodeHex . LazyByteString.pack . cycle) [1, 2, 3]"01020301"
