RSA
About RSA • The RSA algorithm is named after Ron Rivest, Adi Shamir and Len Adleman, who invented it in 1977 • The RSA algorithm can be used for both public key encryption and digital signatures. Its security is based on the difficulty of factoring large integers .
Use of RSA • RSA is still widely used in electronic commerce protocols, and is believed to be secure given sufficiently long keys and the use of up-to-date implementations
Brief about RSA • Key • The term “key” comes from the fact that the secret number you choose works in the same way that a conventional key works
• The algorithm performs its steps using the key to alter the plaintext and convert it to ciphertext. To unlock the encrypted file, you insert the same key and execute. The algorithm reverses the steps and converts the ciphertext back to the original plaintext.
• The original information is known as plaintext, and the encrypted form as ciphertext. The ciphertext message contains all the information of the plaintext message, but is not in a format readable by a human or computer without the proper mechanism to decrypt it; it should resemble random gibberish to those not intended to read it.
