Crypto-Blue: Cipher Node

The Cipher node uses the AES algorithm for encrypting and decrypting message payloads. The following properties can be configured for the node:

• Function: The node's functions, choices include:

  • Encrypt
  • Decrypt

• Algorithm: The algorithm mode to use in the node, the options included are the following: AES-CBC, AES-ECB, AES-CFB, AES-OFB, AES-CTR, AES-GCM

• IV (string): The initialization vector to use, must be in hex format. This can also be configured through the msg.iv field of an injected message.

• IV Size: The size of the initialization vector, options include 128 bit, 192 bit and 256 bit.

• Key (string): The key to use for the encryption / decryption process, must be in hex format. This can also be configured through the msg.key field of an injected message.

• Key Size: The size of the key, options include 128 bit, 192 bit and 256 bit.
