Received "Error (-3) initializing encryption context: Encryption method not implemented" while setting up GoldenGate..

I received following error while setting up encryption for password in GoldenGate.

GGSCI  1> encrypt password y1234 AES128 EncryptKey key1
Password encryption failed...
Error (-3) initializing encryption context: Encryption method not implemented.

Not able to find solution for this. Hence did the following work around....

GGSCI 8> encrypt password y1234  ENCRYPTKEY DEFAULT
Using default key...

Encrypted password:  AACAXXXXXAAWSXTGBG
Algorithm used:  BLOWFISH

Hope this helps..
