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

  • Y This option will read a private OpenSSH format file and print an OpenSSH public key to stdout. Specify the private key with the -f option, yours might be dsa instead of rsa. The name of your private key probably contains which you used. The newly generated public key should be the same as the one you generated before.
  • The private key is usually something like iddsa or idrsa. To regenerate the public key part with just a private key, use the -y switch to the ssh-keygen application and write the output to a corresponding.pub file.

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. A SSH private key as generated by ssh-keygen contains a public key part. How do I retrieve this public key from the private key? I've lost my public key and need to put the contents of this public key in the servers authorizedkeys file and do not want to create a new key pair. Alternatively phrased: how do I create the idrsa.pub file from a idrsa file?

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.

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. Monster hunter generations solo key quests.

Derive Public Key

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
