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.
The Commands to Run Generate a 2048 bit RSA Key. That generates a 2048-bit RSA key pair. Export the RSA Public Key to a File. The -pubout flag is really important. Be sure to include it. Do Not Run This, it Exports the Private Key. Visually Inspect Your Key Files. It is important to visually.
Oct 05, 2007 ssh-keygen can generate both RSA and DSA keys. RSA keys have a minimum key length of 768 bits and the default length is 2048. When generating new RSA keys you should use at least 2048 bits of key length unless you really have a good reason for using a shorter and less secure key.
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.
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.
By default, the private key is generated in PKCS#8 format and the public key is generated in X.509 format.

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.
Auto generate primary key sql. Learn how to define an auto increment primary key in SQL Server. This data tutorial will explain basic table creation and information around using identity a. SQLite AUTOINCREMENT is a keyword used for auto incrementing a value of a field in the table. We can auto increment a field value by using AUTOINCREMENT keyword when creating a table with specific column name to auto increment. I am trying to create a table with an auto-incrementing primary key in Sqlite3. I am not sure if this is really possible, but I am hoping to only have to designate the other fields. For example: CREATE TABLE people (id integer primary key auto increment, firstname varchar(20), lastname varchar(20)). Dec 19, 2014 SQLite – Auto-Increment / Auto Generate GUID David Kittell December 19, 2014 Recently was asked if it’s possible to create an auto-incrementing GUID in SQLite. Mar 18, 2018 this tutorial will show you how to create a table in java db with a column named id as a primary key with auto increment. Skip navigation. How to Generate.
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.
