message digest

A message digest is used to give the document a unique value.

The number represents the size of the message digest.

Finding "collisions", in which two different messages have the same message digest.

There are several reasons to sign such a hash (or message digest) instead of the whole document.

The output from the algorithm is also referred to as a "message digest" or a "check sum".

It takes a message of any length less than 2 bits and returns a 512-bit message digest.

Selecting the optimum element size taking into account the collection of multiple message digests is an open problem.

Message digest - The output of a one-way function when applied to a stream of data.

The message digest algorithm consists of 80 rounds.

In order to use a digital signature, one must use a combination of cryptography and a message digest.

Hashing is a one-way operation that is used to transform data into the compressed message digest.

Using a message digest enhanced with a key (so only a key-holder can check the MAC).

Hash algorithm, sometimes called "message digest"

And so, for example, MD5 stands for Message Digest.

What you look for is what was the message digest, what was the fingerprint technology used for those certificates.

The 512-bit (64-byte) Whirlpool hashes (also termed message digests) are typically represented as 128-digit hexadecimal numbers.

First the passphrase and salt are hashed together, yielding an MD5 message digest.

The expected number of computations required to produce a collision in the 128-bit MD5 message digest function is thus:

The second criterion, finding two different messages that produce the same message digest, known as a collision, requires on average only 2 evaluations using a birthday attack.

For the latter reason the strength of a hash function is usually compared to a symmetric cipher of half the message digest length.

The data to be encoded are often called the "message," and the hash value is sometimes called the message digest or simply digest.

If the attacker does not know the encryption key, he can not modify the message such that message digest value(s) would be valid.

The origin and authenticity of the file received may be checked by digital signatures or by MD5 or other message digests.

Cryptography provides information security with other useful applications as well including improved authentication methods, message digests, digital signatures, non-repudiation, and encrypted network communications.

Let's say the hash function is chosen from a class of hash functions H, which maps messages into D, the set of possible message digests.
