What is a Salted Secure Hash Algorithm ? - Security Wiki
WebIn cryptography, salt refers to some random addition of data to an input before hashing to make dictionary attacks more difficult. Modes Of Introduction The different Modes of … WebCryptography is defined as the practice and study of techniques of secure communication between two parties in the presence of a 3rd party. Encryption is a technique of cryptography wherein a message is encoded such that only authorized parties can read it, converting plaintext into an unintelligible series of letters/numbers. WebIn cryptography, a pepper is a secret added to an input such as a password during hashing with a cryptographic hash function. This value differs from a salt in that it is not stored alongside a password hash, but rather the pepper is kept separate in some other medium, such as a Hardware Security Module.
