Simple command line tool to encrypt/decrypt plain text. Exactly the same algorithm as the TXTcrypt app by Vlad Alexa: vladalexa.com/apps/ios/txtcrypt
You are prompted for a pass-phrase. Internally this is converted to a 256-byte key. The rc4 encryption algorithm is used.
rc4crypt [-h] [-s <suffix>] [<file> [<file> ..]]
Options:
-s <suffix>: generate output filename(s) by appending this suffix to input filename(s). Ignored when reading from stdin.-h: print the help message.
- Read from stdin if no files are specified.
- Output is printed to stdout when reading from stdin.
- Output is printed to stdout if no suffix is specified for input file(s).
- Pass-phrase is read from terminal.
- Decrypt by entering blank pass-phrase at second prompt.
- Uses rc4 (a.k.a. arcfour) algorithm and base64 encoding.
- Encrypts/decrypts plain text into plain text.
