Overview

kpbe is a command line PBE tool for files based on bouncycastle encryption algorithms. It can be used to encrypt and password protect files using standard encryption algorithms like AES, RC4, RC2, Triple DES, Blowfish and Twofish.

Examples

Encrypt a file using 128 bit AES. This will use SHA1 as default digest algorithm to produce the key.

  kpbe -e -a AES -k 128 -p mypassword -o outdir MySecretFile.doc

Encrypt a file using 192 bit Triple DES with SHA-512 digest for key.

  kpbe -e -a DES -k 192 -d SHA512 -p mypassword -o outdir MySecretFile.doc

Decrypt a file encrypted with 128 bit AES

  kpbe -a AES -k 128 -p mypassword -o outdir MySecretFile.doc

Decrypt a file encrypted with 192 bit Triple DES with SHA-512 digest.

  kpbe -a DES -k 192 -d SHA512 -p mypassword -o outdir MySecretFile.doc

Options

Below is the list of all the supported command line options

  -a, --algo=VALUE           Encryption algorithm (AES, RC4, RC2, DES, 
                               BLOWFISH, TWOFISH)
  -m, --mode=VALUE           Block cipher mode (NONE, CBC, CTR, CFB, OFB)
  -b, --padding=VALUE        Block padding (NONE, PKCS7, ISO10126d2, 
                               ISO7816d4, X932, ZEROBYTE)
  -p, --password=VALUE       Encryption password
  -k, --keysize=VALUE        Key size
  -d, --digest=VALUE         Digest algorithm (SHA1, SHA224, SHA256, SHA384, 
                               SHA512, MD2, MD4, MD5)
  -s, --salt=VALUE           Salt phrase
  -i, --iterations=VALUE     Number of iterations
  -e, --encrypt              Encrypt
  -t, --type=VALUE           Type (PKCS12, OPENSSL)
  -o, --output=VALUE         Output directory
  -h, --help                 Help

Some default values used if not specified.

  Key Size = 128
  Digest Algorithm = SHA1
  Mode = CBC
  Padding = PKCS7 (with modes `CTR`, `CFB` and `OFB` no padding is used)
  Salt Phrase = This is a long constant phrase used as salt to create PBE key
  Iterations = 100
  Type = PKCS12

Requirements

kpbe requires .NET 3.5 or later on Windows, or Mono 2.8 or later on Linux/Windows.
