If the length of two MD5 hashes are the same does this mean the strength is equal?

MD5 (Message-Digest algorithm 5) is a widely used cryptographic hash function that always has a 128-bit (16 byte) hash value, so all MD5 hashes must be the same length. As far as "strength" is concerned, hashes are intended to provide a means to check whether a message has been tampered with. MD5 digests have been widely used in the software world to provide some assurance that a transferred file has arrived intact. They are NOT a means for encrypting data. For hash functions, "strength" would have to refer to collision resistance - i.e. difficulty of producing another message with different contents but the same hash.Unfortunately, MD5 is no longer considered to be entirely trustworthy for this purpose; it now that it is easy to generate MD5 collisions (messages with different content but the same hash value). It is possible for the person who created the file to create a second file with the same checksum, so this technique cannot protect against some forms of malicious tampering. Also, in some cases the checksum cannot be trusted (for example, if it was obtained over the same channel as the downloaded file), in which case MD5 can only provide error-checking functionality: it will recognize a corrupt or incomplete download, which becomes more likely when downloading larger files.


What is computed checksum?

A checksum is a part of almost any number you want to include self-verification. Some examples are credit card numbers, bank account numbers, computer file "fingerprints," and computer security codes. See related links for a more detailed explaination of ways checksum is calculated.


What are the two names of the most popular hashing algorithms?

Both SHA-1 and MD5 are good hashing algorithms. The primary difference between the two is speed; MD5 is faster to process than SHA.

What does the computer program Md5sum do?

Md5sum is a program that verifies and calculates 128-bit MD5 hashes. The MD5 checksum is seen as the compact digital fingerprint that is unique to each file.


What is a file MD5 and how can you open it?

It usually is a file that stores checksum or security information that verifies some object on your computer. It most likely is encrypted and you will not be able to use any of the information in the file. Here are some programs that open MD5 files:IsoBusterMD5summerSlavaSoft FSUMMD5 Checksum VerifierMD5 Checker


What are the WAV MD5 files that are sometimes in filesets?

A WAV file is a type of audio file that is typically uncompressed. It stands for Waveform Audio File Format. MD5 is a checksum tool used to ensure the accuracy of the data file.


What is Linux md5sum?

md5sum is a utility that calculates MD5 hashes. It can be used to verify file integrity (in other words, a checksum) like its related utilities sha1sum, and sha256sum.


What does 76f680ac129e1882513db1553e130622 mean in MD5?

The value you get from a MD5 function is the fingerprint of a block of data (any type of file, even programs can be considered data), it allows you to confirm that your copy of the data is the same as the original (no corruption), because slight changes to the input of the MD5 algorithm will produce a different string.


What would one need a checksum for?

A checksum (also known as a hash sum) is a small size datum computed from a block of digital data. One would use a checksum to detect errors that could have been introduced during storage.
