Re: RSA Encryption

The maximum amount of data you can encrypt with a 1024 bit RSA key is 1024 bits of data = 128 bytes. I think PKCS1 padding adds at least 10 bytes before encoding (I might be off on this number?). You want to use padding if you're concerned about the security of your data (pretty much you wan

Hi.. I am using Crypto library of openSSL for RSA encryption and decryption. I am generating RSA parameters for public modulus size of 1024. if I use RSA_public_encrypt() using PKCS1 padding and give an input string to encrypt of lenght 128, I get the following error: "5977:error:0406D06E:rsa routi
