Description

This module contains the combinators implementing the RFC 4648 specification for the Base64 encoding including unpadded and lenient variants

Synopsis

Documentation

encodeBase64 :: ByteString -> ByteString Source #

Encode a ByteString in base64 with padding.

See: RFC-4648 section 4

decodeBase64 :: ByteString -> Either Text ByteString Source #

Decode a padded base64-encoded ByteString

See: RFC-4648 section 4

encodeBase64Unpadded :: ByteString -> ByteString Source #

Encode a ByteString in base64 without padding.

Note: in some circumstances, the use of padding ("=") in base-encoded data is not required or used. This is not one of them. If you are absolutely sure the length of your bytestring is divisible by 3, this function will be the same as encodeBase64 with padding, however, if not, you may see garbage appended to your bytestring in the form of "NUL".

Only call unpadded variants when you can make assumptions about the length of your input data.

See: RFC-4648 section 3.2

decodeBase64Unpadded :: ByteString -> Either Text ByteString Source #

Decode an unpadded base64-encoded ByteString

See: RFC-4648 section 3.2
