RSA(Rivest-Shamir-Adleman) is an Asymmetric encryption technique that uses two different keys as public and private keys to perform the encryption and decryption. With RSA, you can encrypt sensitive information with a public key and a matching private key is used to decrypt the encrypted message. Asymmetric encryption is mostly used when there are 2 different endpoints are involved such as VPN client and server, SSH, etc.
Below is an online tool to perform RSA encryption and decryption as a RSA calculator.
For Java implementation of RSA, you can follow this article.
First, we require public and private keys for RSA encryption and decryption. Hence, below is the tool to generate RSA key online. It generates RSA public key as well as the private key of size 512 bit, 1024 bit, 2048 bit, 3072 bit and 4096 bit with Base64 encoded.
Jun 09, 2019 Thus, there are 2 keys generated during the PGP key creation process: public and private. The public key is the one you will want to share with others (thus the name “public key”). The public key is the one you will want to share with others (thus the name “public key”). Hence, below is the tool to generate RSA key online. It generates RSA public key as well as the private key of size 512 bit, 1024 bit, 2048 bit, 3072 bit and 4096 bit with Base64 encoded. By default, the private key is generated in PKCS#8 format and the public key is generated in X.509 format. PGP Online Tools. Key Management. PGP protocol requires a pair of keys (usually referred as public key and private key to work. Please use below module to either generate or paste the keys. One of the advatages of PGP is that the public key is not secret, and can (should!) be uploaded on public key servers like MIT PGP Public Key Server. Is there a way via an CLI tool or some kind of API to extract the PGP key ID from the PGP public key block? I found the hexa value of the key in the binary file, but I guess the position is based on the key kind/size. Basically, I have the base64 formatted public key and I would like to retrieve the key ID from it, without importing it with GnuPG.
By default, the private key is generated in PKCS#8 format and the public key is generated in X.509 format.
- Apr 23, 2018 PGP gets around this problem using public key encryption. Everyone is assigned two keys: a public one that you can share with everyone and a private one, which you keep to yourself. What makes this system possible is that the codes only work one way. If Key A encrypts a file, Key A cannot reverse the process and decrypt it.
- Generate online private and public key for ssh, putty, github, bitbucket Save both of keys on your computer (text file, dropbox, evernote etc)!!! The generated keys are RANDOM and CAN'T be restored. You can create keys without creating an account.

RSA Encryption and Decryption Online
Below is the tool for encryption and decryption. Either you can use the public/private keys generated above or supply your own public/private keys.
Any private or public key value that you enter or we generate is not stored on this site, this tool is provided via an HTTPS URL to ensure that private keys cannot be stolen.
This tool provides flexibility for RSA encrypt with public key as well as private key along with RSA decrypt with public or private key.

Usage Guide - RSA Encryption and Decryption Online
In the first section of this tool, you can generate public or private keys. To do so, select the RSA key size among 515, 1024, 2048 and 4096 bit click on the button. This will generate the keys for you.
For encryption and decryption, enter the plain text and supply the key. As the encryption can be done using both the keys, you need to tell the tool about the key type that you have supplied with the help of radio button. By default, public key is selected. Then, you can use the cipher type to be used for the encryption. The different cipger options are RSA, RSA/ECB/PKCS1Padding and RSA/ECB/OAEPWithSHA-1AndMGF1Padding. Now, once you click the encrypt button the encrypted result will be shown in the textarea just below the button.
Remember, the encrypted result is by default base64 encoded.
Similarly, for decryption the process is same. Here, you need to enter the RSA encrypted text and the result will be a plain-text. You have both options to decrypt the encryption with public and private keys.

The current OpenPGP standard uses key pairs with RSA, DH/DSS, and ECC asymmetric encryption keys. In this chapter, we are going to generate an RSA key pair with DidiSoft OpenPGP Library for .NET.
Each OpenPGP key pair contains additional information which we have to specify upfront:
- User ID of the key owner, usually in the form “Person name or Organization name <owners_email@website>“
- Size in bits of the encryption key (must be over 1024 and up to 4096)
- list of preferred symmetric encryption algorithms
- list of preferred hash algorithms
- list of preferred compression algorithms
- key expiration date (if the key will be with a time-limited use)
The original PGP(r) software uses a naming convention for delimiting the email in the User ID label with < and > like: “Richard C. <richard.c@site.com>”
Generate RSA based OpenPGP key pair
Below is a short example program that shows how to generate an RSA OpenPGP key pair in a KeyStore object.
C# example
VB.NET example
The above code generates a key pair that does not expire. An overloaded method exists that accepts an expiration date as the last parameter. A key pair can also be generated without using a KeyStore, through a similar method in the PGPKeyPair class.
After the key pair is generated it can be exported. Usually, we will send the public key part of it to our partners.
Below is a screenshot of the key properties after the key is imported in PGP (r) Desktop version 10. Please note that in our example above we have omitted the < > around the email part of the User ID and that’s why PGP(r) displays the name and email part of the User ID together.

Generate Pgp Key Pair
In order to create a key pair asynchronously, we have to use the DidiSoft.Pgp.KeyStoreAsync class which provides the same key creation methods with Async suffixes.
