Code: Select all
Parameter ‘input’ is a BASE64 encoded byte array that consists of two parts:
- First 128 bytes are AES128 symmetric key (aeskey1) encrypted according to RSA 1.5
algorithm using public key of XXXXX Web Service Certificate. Encryption ensures that
only XXXXX Web Service can decrypt XML document.
- The rest is XML document encrypted according to AES128 algorithm using ‘aeskey1’.
‘easkey1’ must be randomly generated by the Client’s host.
