Library for performing common cryptographic operations

There is a newer version: 2.2

- Generate a new 256-bit AES key

  enc -genkey -cipher AES -keysize 256 -out aes.key
  

- Encrypt a file with AES cipher in default CBC mode

  enc -encrypt -cipher AES -key path/to/aes.key \
      -iv 3858f62230ac3c915f300c664312c63f \
      -in path/to/plain.txt -out path/to/cipher.out
        

- Decrypt a file with AES cipher in default CBC mode

  enc -decrypt -cipher AES -key path/to/aes.key \
      -iv 3858f62230ac3c915f300c664312c63f \
      -in path/to/cipher.out -out path/to/plain.txt


- Encrypt a file with AES cipher in OFB mode producing base-64-encoded
  ciphertext

  enc -encrypt -cipher AES -key path/to/aes.key -mode OFB -encoding base64 \
      -iv 3858f62230ac3c915f300c664312c63f \
      -in path/to/plain.txt -out path/to/cipher.out


- Decrypt a base-64-encoded ciphertext file using AES in OFB mode

  enc -decrypt -cipher AES -key path/to/aes.key -mode OFB -encoding base64 \
      -iv 3858f62230ac3c915f300c664312c63f \
      -in path/to/cipher.out -out path/to/plain.txt
      

- Encrypt a file using PKCS#5s2 password-based encryption with AES cipher

  enc -encrypt -cipher AES -pbe Seekr1t -pbemode pkcs5s2 \
      -salt A1B2C3D4E5F6 -keysize 256 \
      -in path/to/plain.txt -out path/to/cipher.out
      

- Decrypt a file that was originally encrypted with PKCS#5s2 password-based
  encryption using AES cipher

  enc -decrypt -cipher AES -pbe Seekr1t -pbemode pkcs5s2 \
      -salt A1B2C3D4E5F6 -keysize 256 \
      -in path/to/cipher.out -out path/to/plain.txt
