Yup. Generating large crypto-grade random primes is not something you want to do frequently (as in, during a connection/transmission protocol). They should last years, and are used to protect just-big-enough temporary keys that use entropy VERY efficiently. But as frequently as you attend a PGP/GPG key-signing, bit efficiency is rather less relevant than gas mileage to get there. -- Bill Ricker bill.n1vux at gmail.com https://www.linkedin.com/in/n1vux
