Web9 de set. de 2016 · The short explanation is: IVs should be random and generated by a CSPRNG. IVs should not be reused. That is, don't encrypt plaintext "A" and plaintext "B" with the same IV. Every record should have its own IV. The IV is not a secret like the key. It can be stored in plaintext along with the cipher text. WebList all cipher suites by full name and in the desired order. Long answer: see below. Re. RSA sorting. You tried: openssl ciphers -v '3DES:+RSA' And on my openssl that is the same as: openssl ciphers -v '3DES:+kRSA' But I think you wanted: openssl ciphers -v '3DES:+aRSA' The "aRSA" alias means cipher suites using RSA authentication.
