... and use it in the new experimental ODF encryption mode. https://www.w3.org/TR/xmlenc-core1/#sec-AES-GCM Unfortunately it turned out that NSS PK11_CipherOp() does not work with CKM_AES_GCM because it is initialized with "context->multi = PR_FALSE" in sftk_CryptInit(), so the one-step functions PK11_Encrypt() and PK11_Decrypt() have to be used. NSS 3.52 also changed a parameter struct definition - see https://fedoraproject.org/wiki/Changes/NssGCMParams - which is not a problem for RHEL or SUSE system NSS since those are rebased, but it is likely a problem for less well maintained Ubuntu LTS, so use the old struct definition which evidently still works with NSS 3.94. NSS 3.52 also added a new PK11_AEADOp() API but it looks like this doesn't support incremental encryption either.
