An algorithm that turns a message into a single string of digits. "One way" means that it is almost impossible to derive the original message from the string of digits. The calculated message digest can be compared with the message digest that is decrypted with a public key to verify that the message has not been tampered with.
In cryptography, an algorithm that generates a fixed string of numbers from a text message. The "one-way" means that it is extremely difficult to turn the fixed string back into the text message. One-way hash functions are used for creating digital signatures for message authentication.
a mathematical function that takes a message string of any length (pre-string) and returns a smaller fixed-length string (hash value)
A hash function that works in one direction: it is easy to compute a hash value from a pre-image, but it is hard to generate a pre-image that hashes to a particular value.
A one-way transformation that converts an arbitrary amount of data into a fixed-length hash. It is computationally hard to reverse the transformation or to find collisions. MD5 and SHA are examples of one-way hash functions.
A function that takes a string of value and converts
A hash function where it is computationally infeasible to determine anything about the input from the output.
one-way function that takes a variable sized input and creates a fixed size output.
A function that converts a message into a fixed string of digits.
A mathematical process performed on data to produce a numeric result called a message digest, which cannot be reversed to produce the original message. See hash and message digest.
