Snap type:

Transform


Description:

This Snap decrypts the binary documents it receives on its input view using the Blowfish algorithm and user-specified encryption parameters.
Note: The default security in the JRE limits the key length for encryption keys. For stronger encryption keys, you would need to manually install the Java Cryptographic Extension JARs on your JCC nodes.

  • Expected Upstream Snaps: Any Snap that produces binary data in the output view such as File Reader or Compress.
  • Expected Downstream Snaps: Any Snap that accepts binary data in the input view such as File Writer or Decompress.


Prerequisites:

    Settings

    Label



    		Required. The name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your pipeline.

    Password



    The string used to generate a secret key and an initialization vector. If the secret key property is set, the password is ignored.
    Example: K1qjoeFQTr


    Secret key


    The secret key used for decryption.
    Example: N0FzAAe4qtY=


    Initialization vector


    The initialization vector used for decryption. It should be in hexadecimal format, and should not be used in ECB mode.
    Example: 296151aacf89c87f


    Cipher mode
    Required.

    The mode of operation for a block cipher.

    The available options include: ECB, CBC, PCBC, CTR, CTS, CFB, CFB8, CFB16, CFB24, CFB32, CFB40, CFB48, CFB56, CFB64, OFB, OFB8, OFB16, OFB24, OFB32, OFB40, OFB48, OFB56, OFB64.

    Default value:  ECB


    Encryption padding
    required

    The encryption padding.

    The available options include: PKCS5PADDING, ISO10126PADDING, NOPADDING.

    Default value:  PKCS5PADDING

    Note
    When the 'NOPADDING' option is selected,  the data is processed in blocks of the same size. It ignores the characters in the end if those are less than the size of the block. As a result, there is a chance of of losing characters at the end.
