|Applies To||RSA Key Manager Server|
RSA Key Manager Client
|Issue||Exception is thrown when trying to encrypt|
com.rsa.kmc.KMException: java.security.InvalidKeyException: java.security.InvalidAlgorithmParameterException: Algorithm parameters required.
|Cause||When creating a Key Class on the RKM Server and specifying the Cipher, if AES is selected for the Algorithm and 256 or 512 is selected for the Key Size, one of the choices for the Mode is XTS. AES XTS mode is only used for the EMC PowerPath product and not supported by RKM Client.|
|Resolution||When creating a Key Class on the RKM Server, ensure that XTS mode is not specified unless the Key Class is going to be used by a product that supports it (such as EMC PowerPath).|
|Notes||For most applications, CBC mode should be used. For more information about the block cipher modes, see the Security Concepts document that is included with RKM Client and RKM Server (doc\security_concepts.pdf) > Symmetric Key Cryptography > Block Ciphers > Modes of Operation.|
