Hello, About commons-codec Hex encoding methods, I suggest adding to Hex static encode method which returns byte[] It will be consistent with other encoding classes that have such method as Base64(same package) and MessageDigest.
I don't see a real reason to use instance method in this case. I would like to contribute this method to library. First asked in https://stackoverflow.com/questions/58128819/apache-common-codec-why-hex-encode-isnt-static/58129148#58129148
