You may generate an RSA private key with the help of this tool. Openssl rsa_generate_key_ex example. Additionally, it will display the public key of a generated or pasted private key.

Add crypto and publickey support for the hash functions SHA224, SHA256, SHA384 and SHA512 and also hmac and rsasign/verify support using these hash functions. Thanks to Andreas Schultz for making a prototype. Own Id: OTP-9908. Optimize RSA private key handling in crypto.

The Data Encryption Standard (DES) defines an algorithm for encrypting and decrypting an 8 byte quantity using an 8 byte key (actually only 56 bits of the key is used). When it comes to encrypting and decrypting blocks that are multiples of 8 bytes various modes are defined (NIST SP 800-38A).

Description

RSA is an asymmetric encryption algorithm. With a given key pair, data that is encrypted with one key can only be decrypted by the other. This is useful for encrypting data between a large number of parties; only one key pair per person need exist. RSA is widely used across the internet with HTTPS.

To generate a key pair, select the bit length of your key pair and click Generate key pair. Depending on length, your browser may take a long time to generate the key pair. A 1024-bit key will usually be ready instantly, while a 4096-bit key may take up to several minutes. For a faster and more secure method, see Do It Yourself below.

CryptoTools.net does not yet have a tool for facilitating the encryption and decryption of data using RSA, but you may Do It Yourself with the instructions below.

Do It Yourself

For these steps, you will need a command line shell with OpenSSL. Ideally, you should have a private key of your own and a public key from someone else. For demonstration, we will only use a single key pair.

Generate Private Key

Run this command to generate a 4096-bit private key and output it to the private.pem file. If you like, you may change the key length and/or output file.

Derive Public Key

Erlang Crypto Generate_key Rsa Program

Given a private key, you may derive its public key and output it to public.pem using this command. (You may also paste your OpenSSL-generated private key into the form above to get its public key.)

Encrypt Data

We can now use this key pair to encrypt and decrypt a file, data.txt.

Decrypt Data

Given the encrypted file from the previous step, you may decrypt it like so.
