RSA (Rivest–Shamir–Adleman) is an algorithm used by modern computers to encrypt and decrypt messages. It is an asymmetric cryptographic algorithm. Asymmetric means that there are two different keys. This is also called public key cryptography, because one of the keys can be given to anyone. The other key must be kept private.

What would you like to do? Embed Embed this gist in your website. The idea of RSA is based on the fact that it is difficult to factorize a large integer. The public key consists of two numbers where one number is multiplication of two large prime numbers. And private key is also derived from the same two prime numbers. So if somebody can factorize the large number, the private key is compromised. Encrypt your AES key (step 1) with your RSA public key, using RSAES-OAEP + MGF1-SHA256; Concatenate your RSA-encrypted AES key (step 3) and AES-encrypted message (step 2). Instead of implementing this yourself, check out EasyRSA. Further reading: Doing RSA in PHP correctly.
I made a PHP script that will let you sort all the available hashes on your system by generation time or by the length of the hash. It shows a general correlation on my system (longer hashes take longer to calculate) but some are faster than others, for example, sha512 makes the (joint) longest hash, but is actually only ninth slowest (from 43
