I'm using AES-256-GCM for authenticated encryption. In order to decrypt, the ruby OpenSSL library requires an
auth_tag parameter (in addition to the key and iv). This, according to the ruby docs, is because authenticated encryption is only supported with associated data (AEAD).
How can I use this
auth_tag to decrypt? The node.js crypto library doesn't have an option for it, so I'm trying to use the openssl command line tool. However, looking at the docs, even that doesn't have an option for supplying the authetication tag.
