Dear All,
I see a strange cipher result. I am using the
following code with a public RSA key:
System.err.println("res = " + toHex(res, p, RSA_OUTPUT));
byte[] temp = cipher.doFinal(res, p, RSA_OUTPUT);
System.err.println("temp = " + toHex(temp, 0, temp.length));
When I run the code on Java SE, I get:
res = XXXX - cipher 64 bytes - XXXX
temp = YYYY - plain 32 bytes - YYYY
When I run the code on Android, I get:
res = XXXX - cipher 64 bytes - XXXX
temp = 01ffffffffffffffffffffffffffffffffffffffffffffffffffffffffff00
YYYY - plain 32 bytes - YYYY
Where does the 01ff...ff00 come from? Can I get rid of it?
Bye
