* openssl: Fix AES-GCM with BoringSSLTobias Brunner2016-10-111-3/+3
| | | | | | | | BoringSSL only supports a limited list of (hard-coded) algorithms via EVP_get_cipherbyname(), which does not include AES-GCM. While BoringSSL deprecated these functions they are also supported by OpenSSL (in BoringSSL a completely new interface for AEADs was added, which OpenSSL currently does not support).

* aead: Support custom AEAD salt sizesMartin Willi2014-03-311-1/+9
| | | | | | | | | The salt, or often called implicit nonce, varies between AEAD algorithms and their use in protocols. For IKE and ESP, GCM uses 4 bytes, while CCM uses 3 bytes. With TLS, however, AEAD mode uses 4 bytes for both GCM and CCM. Our GCM backends currently support 4 bytes and CCM 3 bytes only. This is fine until we go for CCM mode support in TLS, which requires 4 byte nonces.
