What is this encryption, will it be untied?

What is this encryption, can you untie it?
Username=y2ltz5kxajpyzmq=&psw=k2dpazwyaw==&type=1

The username is the account, and the PSW is the password.
Password I know is: 13611438910 after the password can be solved. What is this encryption method?
Thank you

Not knowing the source, only one group is impossible.

psw=k2dpazwyaw==
The string "k2dpazwyaw==" at a glance is probably base64 encoded, decoding the string "Giik"
Should be something like cipher salt, not your so-called password, is the role of combination verification with the password ...

I hope I can help you!

Look like the AES encryption.

Rice has a secret keys, and there is only one group of figures that cannot be solved.
