I am looking for CMS AuthEnvelopedData test vectors for AES-GCM mode. I haven’t seen any ready-to-use test vectors for it. There are test vectors for AES-GCM mode but not for its CMS support.
I even checked open source cryptography libraries which implemented AES-GCM with CMS support (AuthEnvelopedData Content Type), but none of them contained any test vectors that I could extract and use. Openssl doesn’t seem to provide any cms support for aes-gcm either. I also checked the Bouncy Castle cryptography library. In their release notes they state
AES GCM mode is now supported by CMS EnvelopedData.
but the standards (RFC 5083 & RFC 5084) say it should be AuthEnvelopedData. Am I missing something here? Also, in the source code of Bouncy Castle there is a class named
CMSAuthEnvelopedGenerator which is supposed to do the work, but only a few static variables have been defined in the class – no methods defined yet. So, it seems that there are some unfinished business left there.
Warn me if I am wrong but I have come to the decision that very few people are using AES-GCM mode in file encryption and other encryption purposes (except TLS). Because in the other case, how can a library decrypt a file encrypted by another library without using the standard syntax?
I am looking for CMS AuthEnvelopedData test vectors for AES-GCM mode. Can anyone provide (or point me to) test vectors for the CMS content type AuthEnvelopedData (for AES-GCM)?
