Hello,

We have a requirement to encrypt and decrypt the payload sensitive data using a dynamic SHA 256 secret key which is stored in a Vault using a datapower.

Can you suggest ways to encrypt using the dynamic key using XSLT/GatewayScript.

Hi Sandeep,

You would likely be looking at GatewayScript and the crypto module described here https://www.ibm.com/docs/en/datapower-gateway/10.5.x?topic=apis-crypto-module

APIs to encrypt data.

• cipher.final()
• cipher.getAuthTag()
• cipher.getIV()
• cipher.setAAD()
• cipher.setAutoPadding()
• cipher.update()
• crypto.createCipheriv()
• crypto.getCiphers()

APIs to decrypt data.

• crypto.createDecipheriv()
• decipher.final()
• decipher.setAAD()
• decipher.setAuthTag()
• decipher.setAutoPadding()
• decipher.update()
