Q: I am using CAPI Engine in OpenSSL and I did some test. When I use TLS 1.0 or 1.1, during handshake and RSA signing, PKCS padding is chosen. When I use TLS 1.2, RSA signing uses PSS padding.
Funny, a quick lookup of TLS 1.2 contains the following:
Note that there are certificates that use algorithms and/or algorithm
combinations that cannot be ...
What is the difference between cfb and cfb1 and cfb8?
Well, first of all, we need examine what CFB is. Here is what the encryption process is:
Take the previous $n$ bits of ciphertext (where $n$ is the block size of the cipher, for Aria, $n=128$
Send it through the block cipher in encryption mode
Extract $k$ bits of the result, exclusive-or that with the ...
With regard to the structure of RSA key files, and how the public key is related to the private key - you can see that the modulus in the public key file is the product of the two large primes contained in the private key file by doing the following:
Generate a private key:
openssl genrsa -out private.key 2048
Extract the public key from the private key ...
Now that the Qs have been clarified (and yes this isn't really about cryptography, and would be more appropriate on security.SX = application of crypto in systems or superuser = use of programs including security programs like OpenSSL or maybe even stackoverflow)
... Given the example ... 1. Is it correct that EXPPW is the p12 container password and ...
