What is RSA ?
RSA stands for Rivest-Shamir-Adleman. It is widely used for asymmetric encryption algorithm in cryptography.
RSA has two components, one is public key and the other one is private key. You can safely distribute the public key to anyone and use the private key for decryption.
Good part with RSA is security. It is based on large numbers so that it is not easily possible to decrypt. RSA is widely used on the internet for securing the communication for the applications like emails, digital signatures and so on.
In our application, you can select different key sizes like 512, 1024, 2048. Of course higher the key size, the better the security is but it affects the size of the file. It will be completely up to the person how (s)he wants to set up her/his system.
Where to use RSA
It can be used in different security protocol and not limited to:
- Secure Web Browsing (HTTPS): Encrypts data between your browser and websites. This way, you can ensure that data transactions are safe and secured.
- Email Encryption: Different email protocols can use this to make the email communication more secure and protects them from unauthorized access.
- Digital Signatures: Authenticates the origin or documents, and very importantly verifying the sender's identity.
- Secure Shell (SSH) Access: It gives an opportunity for secure remote server management by encrypting session data.
- Software Distribution: By using RSA, you can ensure the authentic of the software packages and not changed by someone else by adding dangerous code in it.
