1 Challenge Handshake Authentication Protocol
A challenge-response authentication protocol for Point-to-Point Protocol (PPP) connections described in RFC 1994. It uses the industry-standard MD5 hashing algorithm to hash the combination of a challenge string issued by the authenticating server and the user's password in the response."بروتوكول ""Challenge Handshake Authentication Protocol"""English-Arabic terms dictionary > Challenge Handshake Authentication Protocol

3 hash
"A fixed-size result that is obtained by applying a one-way mathematical function (sometimes called a hash algorithm) to an arbitrary amount of data. If there is a change in the input data, the hash changes. The hash can be used in many operations, including authentication and digital signing." -
4 message digest
"A fixed-size result that is obtained by applying a one-way mathematical function (sometimes called a hash algorithm) to an arbitrary amount of data. If there is a change in the input data, the hash changes. The hash can be used in many operations, including authentication and digital signing." -
5 key
"In encryption, authentication, and digital signatures, a value used in combination with an algorithm to encrypt or decrypt information." -
6 CHAP
A challenge-response authentication protocol for Point-to-Point Protocol (PPP) connections described in RFC 1994. It uses the industry-standard MD5 hashing algorithm to hash the combination of a challenge string issued by the authenticating server and the user's password in the response. -
7 hash code
"A fixed-size result that is obtained by applying a one-way mathematical function (sometimes called a hash algorithm) to an arbitrary amount of data. If there is a change in the input data, the hash changes. The hash can be used in many operations, including authentication and digital signing."
