New encryption scheme

mensi opened this issue · comments

The new encryption scheme is aes-gcm, 128bit block size, 128bit IV (the same IV as before). The 40 bytes long unencrypted header before the encrypted data is passed as AAD into GCM. The authentication tag is the last 128bits of the encrypted blob.

Thanks for digging this out. I'll try to implement this.
