Twofish Decrypt

Overview

This Snap decrypts the binary documents that it receives on its input view using the Twofish 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.



Account

This Snap uses account references created on the Accounts page of the SnapLogic Manager to handle access to this endpoint. This Snap supports a Symmetric crypto account, or no account. See Configuring Binary accounts for information on setting up accounts that work with this Snap.

Snap views

View Description Examples of upstream and downstream Snaps
Input This Snap has exactly one binary input view.

Stream of binary encrypted data with the encryption details required to decrypt the data streaming in.

 Any Snap that produces binary data in the output view such as File Reader or Compress .
Output This Snap has exactly one binary output view.

Stream of binary decrypted data.

 Any Snap that accepts binary data in the input view such as File Writer or Decompress .
Error

Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter when running the pipeline by choosing one of the following options from the When errors occur list under the Views tab. The available options are:

  • Stop Pipeline Execution Stops the current pipeline execution when an error occurs.
  • Discard Error Data and Continue Ignores the error, discards that record, and continues with the remaining records.
  • Route Error Data to Error View Routes the error data to an error view without stopping the Snap execution.

Learn more about Error handling in Pipelines.

Snap settings

Legend:
  • Expression icon (): Allows using pipeline parameters to set field values dynamically (if enabled). SnapLogic Expressions are not supported. If disabled, you can provide a static value.
  • SnapGPT (): Generates SnapLogic Expressions based on natural language using SnapGPT. Learn more.
  • Suggestion icon (): Populates a list of values dynamically based on your Snap configuration. You can select only one attribute at a time using the icon. Type into the field if it supports a comma-separated list of values.
  • Upload : Uploads files. Learn more.
Learn more about the icons in the Snap settings dialog.
Field / Field set Type Description
Label String

Required. Specify a unique name for the Snap. Modify this to be more appropriate, especially if more than one of the same Snaps is in the pipeline.

Default value: Twofish Decrypt

Example: Twofish Decrypt
Password String The string used to generate a secret key and an initialization vector. If the Secret key property is set, the password is ignored.
Note: This field is currently not encrypted at rest and is saved and exported in plaintext. For any shareable secrets that require encryption at rest, we recommend you use a Secret key in the Symmetric Crypto Account . Using a Symmetric Crypto Account ensures that your sensitive information is protected and secure.

Example: K1qjoeFQTr
Secret key String The secret key that is used for decryption.
Note: This field is currently not encrypted at rest and is saved and exported in plaintext. For any shareable secrets that require encryption at rest, we recommend you use a Secret key in the Symmetric Crypto Account . Using a Symmetric Crypto Account ensures that your sensitive information is protected and secure.

Example: N0FzAAe4qtY=
Initialization vector String The initialization vector used for decryption. It should be in hexadecimal format and should not be used in ECB mode.

Example: 296151aacf89c87f
Cipher mode Dropdown list 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 Dropdown list The encryption padding.

The available options include: PKCS5PADDING, ISO10126PADDING, NOPADDING.

Default value: PKCS5PADDING
Snap execution Dropdown list
Choose one of the three modes in which the Snap executes. Available options are:
  • Validate & Execute: Performs limited execution of the Snap and generates a data preview during pipeline validation. Subsequently, performs full execution of the Snap (unlimited records) during pipeline runtime.
  • Execute only: Performs full execution of the Snap during pipeline execution without generating preview data.
  • Disabled: Disables the Snap and all Snaps that are downstream from it.

Default value: Execute only
