Decrypt Data Using Rsa Between Php And Java Android Issue
I am using a PHP server to encrypt some data and then decrypt it to an Android device. But when I try to decrypt it on the Android device side, I get the following error : javax.c
Solution 1:
You might need to do define('CRYPT_RSA_PKCS15_COMPAT', true).
The following comment block elaborates:
Basically, OpenSSL (and quite potentially Java too) implements PKCS#1 v1.5 whereas phpseclib implements PKCS#1 v2.1. PKCS#1 v2.1 modifies PKCS1 style encryption to make use of randomized padding so no two ciphertext's will ever be the same.
