Can someone give me the code to encrypt and decrypt a string in C#?
I need to implement 256 bit AES encryption, but all the examples I have found online use a "KeyGenerator" to generate a 256 bit key, but I would like to use my own passkey. How can I create my own key...
I see a lot of confusion between hashes and encryption algorithms and I would like to hear some more expert advice about: When to use hashes vs encryptions What makes a hash or encryption algorithm ...
Someone told me that he has seen software systems that would accept MD5 encrypted passwords (through various integrations with other systems), decrypt them, and store them in the systems own database ...
I can't seem to find a nice clean example of using AES 128 bit encryption. Does anyone have some sample code?
I'm currently a student and I'm studying PHP, I'm trying to make a simple encrypt/decrypt of data in PHP. I made some online research and some of them were quite confusing(at least for me). Here's wh...
