[Openid-specs-ab] jwe aes gcm in java

[Axel.Nennker at telekom.de]

Mike,

I implemented AESGCM in Java. The parameters for my example are:

The keybytes are: byte[] N = Hex.decode("cafebabefacedbaddecaf888");
The jweHeader is: {"alg":"A128GCM","iv":"yv66vvrO263eyviI"}

AESGCM jwtHeaderSegment base64:  eyJhbGciOiJBMTI4R0NNIiwiaXYiOiJ5djY2dnZyTzI2M2V5dmlJIn0
AESGCM jwtCryptoSegment base64:  H7I-QNvM8VtMylQfBbbqyrT8xiFcVv-7CZTn-dkXr10dpIOmzjMbqjmbqevK2aAoRu4s5DhU8dbeu8SbRJTCDYYAkYfOo_Hc5NY6B5-VwhnOWc0sres

Result JWE:  eyJhbGciOiJBMTI4R0NNIiwiaXYiOiJ5djY2dnZyTzI2M2V5dmlJIn0.H7I-QNvM8VtMylQfBbbqyrT8xiFcVv-7CZTn-dkXr10dpIOmzjMbqjmbqevK2aAoRu4s5DhU8dbeu8SbRJTCDYYAkYfOo_Hc5NY6B5-VwhnOWc0sres

The code is here:

The JUNIT tests are here:

Maybe you could verify my example with your F# code.
Rob: Could you please check with your php?

Cheers
Axel
