hcrypt, the Harvest Encryption Utility

Using hcrypt, the Harvest encryption utility, you can create the connector's key file. This utility encrypts and decrypts information.

Instructions for running hcrypt appear in context. This section provides additional details about the utility for your information.

The command syntax is:

hcrypt <OPTION> -f <Encrypted File> -i <Input File> -m 
   <Message to Encrypt> -o <Output File> -k <Key File> 
   -p <Encryption Key>

Options

-e = Encrypt the file

-d = Decrypt the file

-g = Generate a new key file (Requires the option -k followed by file name)

-h = Help

-v = Display version

-f = Final encrypted file

-i = Input file that needs to be encrypted

-m = One line message to encrypt

-o = File name to write the decrypted value. Works only with -d option (Optional)

-k = Encryption key file (Optional)

-p = Encryption key (Optional)

Rules

• You should specify only one option between -m and -i
• You should specify only one option between -d and -e
• You should specify only one option between -k and -p
• If the encrypted file already exists then the new information will be appended to it.
• If you have not specified -o option, then the decrypted message is written to the console.
• If you did not specify an encryption file, then use the default key.
• If you used a non-default encryption key to encrypt the data, then you must use the same key to decrypt it.

Examples:

• Encrypt a file

  hcrypt -e -f "Encrypted.enc" -i "Input File"
  

• Encrypt a message using the privatekey.key

  hcrypt -e -f "Encrypted.enc" -m "Hello World" -k  "privatekey.key"
  

• Encrypt a message using the passed key

  hcrypt -e -f "Encrypted.enc" -m "Hello World" -p "My Key"
  

• Decrypt a file

  hcrypt -d -f "Encrypted.enc"
  

  Note: The decrypted message is printed back to the console.

  Decrypt a file

  hcrypt -d -f "Encrypted.enc" -o "Results.txt"
  

  Note: The decrypted message is written to Results.txt.

• Generate a new key file

  hcrypt -g -k "NewKey.key"
  

• Decrypt a message using the passed key

  hcrypt -d -f "Encrypted.enc" -m "Hello World" -p "My Key"
