摘要: A hashing method and system. The method comprises receiving by a computing system first source data. A first hash function is applied to first source data. A first hash output is generated by the first hash function as a result of applying the first hash function to first source data. The computing system performs an operation relating the first source data with at least a portion of the first hash output to generate second source data. The first hash function is applied to the second source data. A second hash output is generated as a result of applying the first hash function to the second source data.

摘要: A hashing method and system. The method comprises receiving by a computing system, a user password. The computing system generates a first hash for the user password. The computing system generates a second hash for a system parameter and performs an operation relating the first hash to the second hash to generate a first combination value. The computing system generates a third hash for the first combination value. The computing system receives a specific password for requesting access to the computing system. The computing system generates a fourth hash for said specific password and performs an operation relating the fourth hash to the second hash to generate a second combination value. The computing system generates a fifth hash for the second combination value. The third hash is compared to the fifth hash to determine that the third hash matches the fifth hash. Access is enabled to the computing system.
