A modern Base64 library.

A performant, featureful RFC 4648 and 7049-compliant Base64 implementation

Base64

Base64 encoding and decodings.

For the companion optics and pattern synonyms, see base64-lens.

Summary

The following types are supported for both std, padded url-safe, and unpadded url-safe alphabets:

• Data.ByteString
• Data.ByteString.Lazy
• Data.ByteString.Short
• Data.Text
• Data.Text.Lazy
• Data.Text.Short

Additionally this library has

• Better performance than base64-bytestring for encode and decode.
• Optics for handling more complex structures with Base64 representations via the base64-lens package
• Checks for both validity and correctness of Base64 and Base64url encodings
• Rejects non-canonical encodings that do not roundtrip in other base64 libraries like ZE==.

There are no dependencies aside from those bundled with GHC, text-short, and the ghc-byteorder re-export.
