Issue in Android Encryption using RSA/ECB/PKCS1padding. It gives different results in Java and Android -

i facing 1 strange issue. server giving me public key encrypt user name , password.

it giving different result if use rsa/ecb/pkcs1padding (cipher cipher = cipher.getinstance("rsa/ecb/pkcs1padding")) algorithm. same algorithm using in java server , android, gives different results.

if use rsa/ecb/nopadding algorithm, both results same , working fine. need implement rsa/ecb/pkcs1padding in android.

please identify issue ?

thanks.

it's because of padding function, when use pkcs#1 padding , other ways,it generate random number , make cipher text different each time.
