Public-key cryptography         
  • digitally signed]] with Alice's private key, but the message itself is not encrypted.
1) Alice signs a message with her private key.
2) Using Alice's public key, Bob can verify that Alice sent the message and that the message has not been modified.
  • In an asymmetric key encryption scheme, anyone can encrypt messages using a public key, but only the holder of the paired private key can decrypt such a message. The security of the system depends on the secrecy of the private key, which must not become known to any other.
  • symmetric cipher]] which will be, in essentially all cases, much faster.

Public-key cryptography, or asymmetric cryptography, is a cryptographic system that uses pairs of keys. Each pair consists of a public key (which may be known to others) and a private key (which may not be known by anyone except the owner).

<cryptography> A piece of data used in {private-key cryptography} and public-key cryptography. In the former the private key is known by both sender and recipient whereas in the latter it is known only to the sender. (2008-02-07)

<cryptography> (PKE, Or "public-key cryptography") An encryption scheme, introduced by Diffie and Hellman in 1976, where each person gets a pair of keys, called the public key and the private key. Each person's public key is published while the private key is kept secret. Messages are encrypted using the intended recipient's public key and can only be decrypted using his private key. This is often used in conjunction with a digital signature. The need for sender and receiver to share secret information (keys) via some secure channel is eliminated: all communications involve only public keys, and no private key is ever transmitted or shared. Public-key encryption can be used for authentication, confidentiality, integrity and non-repudiation. RSA encryption is an example of a public-key cryptosystem. {alt.security FAQ (http://cis.ohio-state.edu/hypertext/faq/bngusenet/alt/security/top.html)}. See also knapsack problem. (1995-03-27)
Public-Key Cryptography Standards         
GROUP OF PUBLIC-KEY CRYPTOGRAPHY STANDARDS DEVISED AND PUBLISHED BY RSA SECURITY INC
Public-Key Cryptography Standards; PKCS10; PKCS7; Public-Key Cryptography Standard
<cryptography, standard> (PKCS) A set of standards for public-key cryptography, developed by {RSA Data Security, Inc.} in cooperation with an informal consortium, originally including Apple, Microsoft, DEC, Lotus, Sun and MIT. The PKCS have been cited by the {OSI Implementers' Workshop} (OIW) as a method for implementation of OSI standards. PKCS includes both algorithm-specific and algorithm-independent implementation standards. Many algorithms are supported, including RSA and Diffie-Hellman key exchange, however, only the latter two are specifically detailed. PKCS also defines an algorithm-independent syntax for digital signatures, digital envelopes, and extended digital certificates; this enables someone implementing any cryptographic algorithm whatsoever to conform to a standard syntax, and thus achieve interoperability.

Key (cryptography)         
PIECE OF INFORMATION IN CRYPTOGRAPHY
Cryptography/Key; Secret key; Encryption key; Cryptographic keys; Cryptographic key; Key (cryptology); Cryptovariable; Cryptovariables
A key in cryptography is a piece of information, usually a string of numbers or letters that are stored in a file, which, when processed through a cryptographic algorithm, can encode or decode cryptographic data. Based on the used method, the key can be different sizes and varieties, but in all cases, the strength of the encryption relies on the security of the key being maintained.

In public-key cryptography, a public key fingerprint is a short sequence of bytes used to identify a longer public key. Fingerprints are created by applying a cryptographic hash function to a public key.
