WebMay 20, 2024 · RSA is a public key or asymmetric key algorithm. RSA stands for Rivest, Shamir and Adleman the three inventors of RSA algorithm. Each user has to generate two keys public key known to all and private key only known to him. Encryption is done using the public key of the intended receiver. A receiver cracks the message using its private key. WebTo encrypt a private key using triple DES: openssl rsa -in key.pem -des3 -out keyout.pem To convert a private key from PEM to DER format: openssl rsa -in key.pem -outform DER -out keyout.der To print out the components of a private key to standard output: openssl rsa -in key.pem -text -noout To just output the public part of a private key: RSA (Rivest–Shamir–Adleman) is a public-key cryptosystem that is widely used for secure data transmission. It is also one of the oldest. The acronym "RSA" comes from the surnames of Ron Rivest, Adi Shamir and Leonard Adleman, who publicly described the algorithm in 1977. An equivalent system was … See more The idea of an asymmetric public-private key cryptosystem is attributed to Whitfield Diffie and Martin Hellman, who published this concept in 1976. They also introduced digital signatures and attempted to apply number theory. Their … See more Proof using Fermat's little theorem The proof of the correctness of RSA is based on Fermat's little theorem, stating that a ≡ 1 (mod p) for any integer a and prime p, not dividing a.
