In order to reduce encryption or signature verification time, it is useful to use a small public exponent (). In practice, common choices for are 3, 17 and 65537 . These values for e are Fermat primes, sometimes referred to as and respectively . They are chosen because they make the modular exponentiation operation faster. Also, having chosen such , it is simpler to test whether and while generating and testing the primes in step 1 of the key generation. Values of or that fail this test ca… WebAttacks on RSA decryption implementations thru side channels in padding check, including Bleichenbacher's attack on RSAES-PKCS1-v1_5, are practical for very low e like e = 3, and seem adequately mitigated for e = 65537. Implementations vulnerable to that were the norm when today's RSA key generation standards have been written. credit services near me
