Decryption of string using external AES256 key

Hi Devcentral,

 

I would like to know if anyone tried to create a proc that decrypt a string using AES-256 in ECB mode (basically I have an encrypted string produced by an LDAP server that I would like to decrypt ).

 

If I understood correctly AES::decrypt uses CWC mode so is not usable in this case because:

 

1. Its CBC mode
2. The encrypted string need to be calcuated on the BIG-IP

Does anyone have any idea in order to accomplish that?

 

Thanks in advance,

 

Best Regards.
