But that's not really due to using a small e; rather, it is due to not applying a proper padding.

Furthermore, RSA key sizes grow very fast if you require more key strength. RSA-3072 is providing about 128 bit security, but you need to go over 16Kbit of key size to reach 256 bits. raymond james grand junction co

"WebThe Rivest-Shamir-Adleman (RSA) Algorithm is a public-key crypto algorithm. It is based on the principle that prime factorization of a large composite number is tough. Only the private key of the receiver can decrypt the cipher message. RSA is a key pair generator. Choose two different large random prime numbers p and q Calculate n = p q " - Rsa with python
