Decrypts the given encrypted value using an asymmetric key specified by the key path and algorithm. The key path will be in the format of [ProviderName]/KeyIdentifier and should be an asymmetric key stored in the specified CSP provider. The valid algorithm used to encrypt/decrypt the CEK is 'RSA_OAEP'.
