Key wrapping is a process that encrypts one key using another key. It can use either symmetric or asymmetric cryptography, depending on the context. CCM and GCM are two AE modes. CCM stands for Counter with CBC-MAC. GCM stands for Galois/Counter mode of operation. Key wrapping may also refer to a deterministic, symmetric-key authenticated-encryption algorithm that protects cryptographic keys. According to RFC 5084, AES-CCM and AES-GCM can be used safely with the CMS authenticated-enveloped-data content type.
