[ptxdist] [PATCH 2/2] strongswan: aes-gcm support enabled

[Bruno Thomsen]

Enabled support for AES-GCM (Galois/Counter Mode) which is an
Authenticated Encryption with Associated Data (AEAD) cipher.

This seems like a good moment to reiterate that everything less than
TLS 1.2 with an AEAD cipher suite is cryptographically broken.
