Readme for base64-1.0

[back to package description]

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.
