RSA CRYPTER (KEY GENERATOR & ENCRYPTION & DECRYPTION) for JavaScript

> CRYPT / PASSWORD TOOLS (WEB APP) > RSA CRYPTER (Public-key cryptography) >
▼　 DESCRIPTION

This tool is a web application that generates public-keys for RSA, encrypts & decrypts.
RSA Rivest Shamir Adleman

RSA (Rivest Shamir Adleman) is a public-key cryptosystem that is widely used for secure data transmission.
How to securely send and receive files (Pass a public key to encrypt)

When sending a file from A to B
1. B generates public-keys with a passphrase
2. Pass a public-key of B to A
3. A encrypts a file with a received public-key
4. Pass a file that A encrypted to B
5. Decrypt a file received by B with a passphrase

When sending a file from B to A
1. A generates public-keys with a passphrase
2. Pass a public-key of A to B
3. B encrypts a file with a received public-key
4. Pass a file that B encrypted to A
5. Decrypt a file received by A with a passphrase

※ Passphrase and BIT should be the same for both public-key generation and file decryption.
※ INPUT TYPE needs to make the same select for A and B.
PROCESS Generate public-key ⇒ Encryption file ⇒ Decryption file

How to generate public-key
1. Select KEY GENERATE
2. Select BIT (size)
3. Input PASSPHRASE (Used even when decrypting)
4. Press RUN BUTTON
5. Copy PUBLIC KEY (Pass this public-key)

How to encrypt file
1. Select ENCRYPTION
2. Input the received public-key
3. Select INPUT TYPE (FILE)
4. Input file to be encrypted
5. Press RUN BUTTON
6. Download encrypted file (Pass this file)

How to decrypt file
1. Select DECRYPTION
2. Select BIT (size)
3. Input PASSPHRASE (Same as when you generated a public-key)
4. Select INPUT TYPE (FILE)
5. Input received file
6. Press RUN BUTTON
7. Download decrypted file (Completion)

※ The generation of a public-key and the decryption of a file are runned by the same person. Encryption of a file will be runned by another person.
