You are probably referring to the MD5 Message-Digest Algorithm which is a widely used cryptographic hash function that produces 128-bit (16-byte) hash values. A hash function is an algorithm that takes a block of data and creates a string of data (hash) of fixed length. By running the algorithm on a received block of data, a user should be able to detect whether the data has been altered because a given block of data should always yield the same hash unless it has been altered. Ideally a hash function will allow easy computation of the hash value for any given message but make it hard to start with the hash value and come up with a message that will yield that hash value. It should also be so difficult to modify a message without changing the hash that the time and effort necessary to do it exceeds the value of doing it and extremely difficult or impractical to find two different messages with the same hash.
Note that by its nature the MD5 hash is not supposed to allow you to recover the message that was processed. Usually when we use the word "encryption" we are talking about a process where a message is converted to something called "cyphertext" which is unreadable unless you have the right algorithm and key to decrypt it and convert it back to the original message. In this respect it is more accurate to refer to "MD5 hashing" rather than MD5 encryption. See the attached link for more details on the MD5 hash.

How do you decyrpt the MD5 hash string?
The MD5 hash algorithm is a cryptographic hash function, not an encryption method. A cryptographic hash function converts a message of variable length to a fixed size of 'hash,' usually done to check the integrity and authenticity of the original message, and not transmit the message itself in a unreadable encrypted way. The message is also sent ALONG with the hash, usually to ensure that the original message has not been altered en route. Thus it does not have enough information to actually retrieve the message itself. (although it can if the size of the message is the size of the hash, it is never the case.) Decrypting the MD5 hash string will not yield the information that was used for its creation anyways.
Why SHA more secure than MD5?
pls post d ans
Which two technologies can provide data integrity in a vpn connection?
-md5 -hsa-1
Public key encryption is also known as asymmetric encryption?
Yes. Public Key encryption (or asymmetric encryption) requires a pair of keys; a public and a private key for exchanging data in a secure manner.
Which level of encryption does WEP provide in high encryption mode?
128-bit
Can someone decrypt this md5 hash b2a6f48ab5c7eedbe8f31b7d3c2469ce please?
Unfortunately, md5 encryption can NEVER decrypted, that is the whole point of it!
Which encryption technology uses the SHA and MD5 algorithms?
Hash Encoding
Which is better encryption algorithm among DES Blowfish and MD5?
MD5 isn't a encryption algorithm, it's a hashing algorithm. Encryption will 'hide' the meaning of the encrypted text, while MD5 will 'add up' all the text to come up with a number. This number can be compared to another time this file was 'added up', to provide a simple kind of check to see if the text has been changed or if it is the same.
How do decrypt the password in php?
If the encryption is applied using md5, decrypting is normally impossible (emphasizes on normally).
How do you decode to encode using md5 funcation in php?
md5() is one-way encryption method. Example: $test_string="php"; $md_encoded_string=md5($test_string); But, you can't decode the string back to php.So, if you need to check the entered string is php or not $user_entered_string=md5($_POST['user_input']); if($md_encoded_string == $user_entered_string) { echo "input matched"; }
What are the available encryptions in PHP?
PHP has built-in one way hashing using the md5 function. Additional encryption capabilities are available using the Mcrypt extension.
How do you crack the MD5 on learntohack dot co dot UK?
the md5 in this site is fake md5
What is the bit for MD5?
MD5 is one of the ways of encrypting passwords and making them secure than leaving them plain. MD5 is of bit 32.
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.
How secure is MD5?
MD5 password scrambler used to be secure but now is no longer secure.
What is the purpose of MD5 hash calculation?
MD5 check sum is unique for a file content and is used to check the integrity of the file content. If file is to be transferred using network, recipient can calculate the MD5 hash and check it with the MD5 check sum of sender, if both are same, he can be sure of non-corruption of file in transit.
Example of md5 algorithm?
