> The {{EncryptContent}} Processor current supports {{AES_CBC}} as an option for the {{Encryption Algorithm}} property. This option translates to the use of {{AES/CBC/PKCS7Padding}} as the cipher algorithm for encryption or decryption.
> Supporting decryption using {{AES/CBC/NoPadding}} will allow integration with external systems requiring the use of that particular cipher algorithm. Encryption support for {{AES/CBC/NoPadding}} is not recommended due to potential padding vulnerabilities in AES-CBC as well as the requirement for padding input to match the required cipher block size.
