Okay so this hands you a legacy string to key function — the one PEM files use. (The page spells it "legancy" and honestly, iconic typo, we keep it.) 🎀

🚨 Bestie, listen: new protocols should use new string to key functions like NIST SP56-800A or PKCS#5 v2.0 (peep PKCS5_PBKDF2_HMAC_SHA1()). This one is legacy for a reason. Don't build your new thing on it, fr fr.

  • engine — crypto engine to use, NULL to select default.
  • key — the crypto key to use, NULL will use the previous value.

💅 int EVP_CipherUpdate (EVP_CIPHER_CTX * ctx, void * out, int * outlen, void * in, size_t inlen)

See EVP Cipher for an example how to use this function.

Returns: 1 on success.

If there in no spare bytes in the left from last Update and the input length is on the block boundery, the EVP_CipherUpdate() function can take a shortcut (and preformance gain) and directly encrypt the data, otherwise we hav to fix it up and store extra it the EVP_CIPHER_CTX.
