Can I decrypt data which is encrypted by Keyczar using Google Tink?

Question

I have been using Google Keyczar for encrypting data in my JAVA app. And I want to change the crypto solution to Google Tink.

But the problem is the already encrypted data by Keyczar. Can I decrypt them by Tink?

If yes, I want to change the crypto solution from Keyczar to Tink. If no, I have to think about another solution.

Thank you.

Answer 1

I did it. Keyczar is using AES. So I use TinyAES. Keyczar is also using HMAC. So I use HMAC of avr-crypto-lib.

Just one thing is I have to extract the key from Keyczar key.
