AES Tasks
Properties Configuration Settings
The AES Task can be used to encrypt and decrypt data for regular transport.
Remarks
The AES Task contains an encoder and a decoder that receive SSIS ADO tables from the SSIS Package and perform cryptographic operations on the data. The encoder will produce an encrypted file that the decoder can then decrypt, making it possible to add secure storage to your business process.
Configuration
Since AES is a symmetric-key algorithm, the settings for the Encode operations and Decode operations are the exact same.
First set the KeySize to determine the strength of the cipher to be used. Next, set the KeyPassword to allow the task to generate the cryptographic Key and IV. Alternatively, you may set the Key and IV properties directly. Note that the same password may be used for the encoder and decoder to generate the same key and IV.
You can change how the cryptography is performed by setting the CipherMode and PaddingMode properties.
