  • parse keys that include 0's e.g. converted from hexadecimal inputs
  • handle arbitrary binary plaintext/ciphertext without assuming they should be NULL terminated strings (which are handled properly anyhow)
  • support PKCS#5 padding and use memcpy instead of looping over bytes

support arbitrary binary input and output

NULL terminated strings will be encrypted/decrypted with a '\0'
character as part of their payload anyhow, so do not add superfluous
'\0' termination to plaintext/cyphertext since it breaks arbitary binary
inputs
