Questions tagged [apache-commons-codec]

Apache Commons Codec provides implementations of common encoders and decoders such as Base64, Hex, Phonetic and URLs.

Apache Commons Codec was originally designed to be the definitive Base64 encoder, as there existed many different implementations.

While this package contains an abstract framework for the creation of encoders and decoders, Codec itself is primarily focused on providing functional utilities for working with common encodings.
