Module cipher 

CipherAlg — EVP_CIPHER algorithm descriptor.

Phase 3.2 delivers CipherAlg; Phase 4.2 extends this module with CipherCtx<Dir>, AeadEncryptCtx, and AeadDecryptCtx.

Structs

AeadDecryptCtx

AEAD decryption context.

AeadEncryptCtx

AEAD encryption context (GCM, CCM, ChaCha20-Poly1305).

CipherAlg

An OpenSSL symmetric cipher algorithm descriptor (EVP_CIPHER*).

CipherCtx

Stateful symmetric cipher context.

Decrypt

Marker type for decrypt direction.

Encrypt

Marker type for encrypt direction.

Traits

IsEncrypt

Helper trait that routes to the correct EVP_Encrypt* or EVP_Decrypt* functions.
