Interface CompressionCodecResolver

public interface CompressionCodecResolver

Looks for a JWT zip header, and if found, returns the corresponding CompressionCodec the parser can use to decompress the JWT body.

JJWT's default JwtParser implementation supports both the DEFLATE and GZIP algorithms by default - you do not need to specify a CompressionCodecResolver in these cases.

However, if you want to use a compression algorithm other than DEF or GZIP, you must implement your own CompressionCodecResolver and specify that when building and parsing JWTs.

0.6.0
