RSA is an asymmetric algorithm that can be used for encryption and signing. The related algorithm for creating a shared secret symmetric key (key exchange) is Diffie-Hellman. RSA …

Jun 2, 2021 · The actual RSA algorithm is this, with small optimizations. For instance, turns out (q-1) (p-1) is not the best number we can use for this and we can use a smaller number that …

Apr 27, 2023 · While the RSA algorithm is deprecated, it's still widely used by all OSes still supported, but don't necessarily have OpenSSL3. 0.x available in their repos. There's no huge …

Whereas RSA is actually two algorithms (one for asymmetric encryption and another for signatures), Diffie-Hellman is not an asymmetric encryption algorithm per say, only a key …

RSA - Given n, calculate p and q? This may be a stupid question & in the wrong place, but I've been given an n value that is in the range of 10 42. I have to find p and q but the only way I …

Yes, cryptographic algorithms can and have been patented. If you patent an algorithm, people will avoid using it, as we have good patent-free cryptography today.

Oct 25, 2022 · RSA is the default so most people create RSA certificates because they don't know to change it when generating the certificate signing request in the Palo GUI. Your CA just …

Don't use rsa for the real data - randomly generate a key, encrypt the key with rsa, and use the key to encrypt with another algorithm.

Jul 6, 2023 · Does anyone actually use RSA anymore? We hear all the time about how shor’s algorithm is a killer app for quantum computers, but it seems like everyone is moving over to …

But even that isn't enough, because instead of one character of plain text ("B" in his case), you do a group of letters at a time, typically something like 128 or 256. The math just gets immense if …
