The RSA Algorithm. The Rivest-Shamir-Adleman (RSA) algorithm is one of the most popular and secure public-key encryption methods. The algorithm capitalizes on the fact that there is no efficient way to factor very large (100-200 digit) numbers. RSA encryption usually is only used for messages that fit into one block.

Advanced Encryption Standard(AES) is a symmetric encryption algorithm. AES is the industry standard as of now as it allows 128 bit, 192 bit and 256 bit encryption.Symmetric encryption is very fast as compared to asymmetric encryption and are used in systems such as database system. Following is an online tool to generate AES encrypted password and decrypt AES encrypted password. It provides two mode of encryption and decryption ECB and CBC mode.

Usage Guide

Any plain-text input or output that you enter or we generate is not stored on this site, this tool is provided via an HTTPS URL to ensure that text cannot be stolen.

For encryption, you can either enter the plain text, password, an image file or a .txt file that you want to encrypt. Now choose the block cipher mode of encryption. ECB(Electronic Code Book) is the simplest encryption mode and does not require IV for encryption. The input plain text will be divided into blocks and each block will be encrypted with the key provided and hence identical plain text blocks are encrypted into identical cipher text blocks. CBC mode is highly recommended and it requires IV to make each message unique. If no IV is entered then default will be used here for CBC mode and that defaults to a zero based byte[16].

The AES algorithm has a 128-bit block size, regardless of whether you key length is 256, 192 or 128 bits. When a symmetric cipher mode requires an IV, the length of the IV must be equal to the block size of the cipher. Hence, you must always use an IV of 128 bits (16 bytes) with AES.

AES provides 128 bit, 192 bit and 256 bit of secret key size for encryption. Things to remember here is if you are selecting 128 bits for encryption, then the secret key must be of 16 bits long and 24 and 32 bits for 192 and 256 bits of key size. Now you can enter the secret key accordingly. By default, the encrypted text will be base64 encoded but you have options to select the output format as HEX too.

Similarly, for image and .txt file the encrypted form will be Base64 encoded.

Below is a screenshot that shows a sample usage of this online AES encryption tool.

AES decryption has also the same process. By default it assumes the entered text be in Base64. The input can be Base64 encoded or Hex encoded image and .txt file too. And the final decrypted output will be Base64 string. If the intended output is a plain-text then, it can be decoded to plain-text in-place.

But if the intended output is an image or .txt file then you can use this tool to convert the base64 encoded output to an image.

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

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

Serial Key Generator

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