The method became known as the Diffie-Hellman key exchange. RSA (Rivest–Shamir–Adleman) is another notable public-key cryptosystem. Created in 1978, it is still used today for applications involving digital signatures. [17] Using number theory, the RSA algorithm selects two prime numbers, which help generate both the encryption and ...
The Massey–Omura method uses exponentiation in the Galois field GF(2 n) as both the encryption and decryption functions. That is E(e,m)=m e and D(d,m)=m d where the calculations are carried out in the Galois field. For any encryption exponent e with 0<e<2 n-1 and gcd(e,2 n-1)=1 the corresponding decryption exponent is d such that de ≡ 1 ...
There are two schemes for encryption and decryption: RSAES-PKCS1-v1_5: older Encryption/decryption Scheme (ES) as first standardized in version 1.5 of PKCS #1. Known-vulnerable. RSAES-OAEP: improved ES; based on the optimal asymmetric encryption padding (OAEP) scheme proposed by Mihir Bellare and Phillip Rogaway. Recommended for new ...
Decryption is the reverse, in other words, moving from the unintelligible ciphertext back to plaintext. A cipher (or cypher) is a pair of algorithms that carry out the encryption and the reversing decryption. The detailed operation of a cipher is controlled both by the algorithm and, in each instance, by a "key".

A common flawed delivery mechanism for one-time-pad is a standard hybrid cryptosystem that relies on symmetric key cryptography for pad encryption, and asymmetric cryptography for symmetric key delivery. Common secure methods for one-time pad delivery are quantum key distribution, a sneakernet or courier service, or a dead drop.
In cryptography, ciphertext or cyphertext is the result of encryption performed on plaintext using an algorithm, called a cipher. [1] Ciphertext is also known as encrypted or encoded information because it contains a form of the original plaintext that is unreadable by a human or computer without the proper cipher to decrypt it.
