  • Most web sites and applications store their user passwords into databases with MD5 encryption.[1]
  • Unfortunately, there is a way to decrypt a MD5 hash, using a dictionary populated with strings and their MD5 counterpart.[1]
  • The paper presents a hardware implementation of the MD5 hash generator.[2]
  • The generator comprises MD5 processing unit, data exchange interface and memory block for storing input messages.[2]
  • A general concept and implementation of the MD5 generator modules is described.[2]
  • Presented solution is based on the finite state machines; its performance is compared with other MD5 implementations.[2]
  • In this paper we present a new powerful attack on MD5 which allows us to find collisions efficiently.[3]
  • We used this attack to find collisions of MD5 in about 15 minutes up to an hour computation time.[3]
  • MD2, MD4, and MD5 are recommended only for compatibility with existing applications.[4]
  • dCode uses its databases of words (2 million potential passwords) whose MD5 hash has already been pre-calculated.[5]
  • Using salted md5 for passwords is a bad idea.[6]
  • MD5 was designed by Ron Rivest, who is also the `R' in `RSA' in 1991.[7]
  • The following example shows a valid MD5 resinfo extension with two MD5 hashes of the referenced information resource.[7]
  • This is known as an MD5 "collision".[8]
  • An effective and efficient countermeasure to remediate this vulnerability is to stop using MD5 for digital signatures.[8]
  • Acceptable alternatives to replace MD5, such as SHA-1, are widespread or, like SHA-2, at least becoming rapidly available.[8]
  • It would be best to stop using MD5 for the creation of certificates altogether, as its continued use may lead to severe security problems.[8]
  • MD5 Checksum is used to verify the integrity of files, as virtually any change to a file will cause its MD5 hash to change.[9]
  • After a block of 16 words has been input, REQ is deasserted as the MD5 core computes the message digest.[10]
  • If no infile or -d option is specified or infile is a single “ - ”, md5 reads from standard input.[11]
  • RSA Data Security Inc. The MD5 message-digest algorithm produces a 128-bit "fingerprint" or "message digest" of the input.[12]
  • MD5 was created to be a digital signature for applications where large files can be verified by checking the MD5 hash output.[12]
  • The MD5 checksum that is created can be used as a compact digital fingerprint for the associated file.[12]
  • An MD5 file has been added to many of the datasets to verify that the data have not been corrupted or changed during the download process.[12]
  • It has since 2005 been easy to generate different messages that produce the same MD5 digest.[13]
  • This function will concatenate all arguments, calculate the MD5 digest of this "message", and return it in binary form.[13]
  • Same as md5(), but will return the digest in hexadecimal form.[13]
  • Same as md5(), but will return the digest as a base64 encoded string.[13]
  • An MD5 checksum is a 32-character hexadecimal number that is computed on a file.[14]
  • After downloading an Altera software installation package, you can compute the MD5 checksum on the installation file.[14]
  • Use the computed MD5 checksum to compare against the MD5 checksum provided for that installation file on the download page.[14]
  • md5 is older and more commonly used than sha1 but sha1 is considered more secure.[15]
  • PT - SHA and MD5 are both enhanced digests based upon the MD4 algorithm.[15]
  • prints the MD5 digest of the given file in hexadecimal to stdout.[15]
  • Computes an MD5 value of s and returns its string representation.[16]
  • This function initializes md5.[17]
  • The ComputeHash methods of the MD5 class return the hash as an array of 16 bytes.[18]
  • Note that some MD5 implementations produce a 32-character, hexadecimal-formatted hash.[18]
  • Due to collision problems with MD5/SHA1, Microsoft recommends SHA256 or SHA512.[18]
  • Consider using the SHA256 class or the SHA512 class instead of the MD5 class.[18]
  • However, as the official documentation indicates, the reason is rather to advise not to use MD5 in general for security concerns.[19]
  • This means we can still use this method if we, for example, need to integrate with the legacy system that requires MD5.[19]
  • There are different ways in Java API and other third-party APIs like Apache commons and Guava to generate the MD5 hash.[19]
  • This online tool allows you to generate the MD5 hash of any string.[20]
  • MD5 is still being used today as a hash function even though it has been exploited for years.[21]
  • Does your content management system rely on the MD5 hashing scheme for securing and storing passwords?[21]
  • Initially created in 1991 by cryptographer and MIT professor Ronald Rivest, MD5 is technically known as the Message-Digest Algorithm.[21]
  • As a hash function, MD5 maps a set of data to a bit string of a fixed size called the hash value.[21]
  • MD5 has been strongly deprecated as a means of securely signing data, given the multiple weaknesses discovered in the algorithm.[22]
  • MD5 is the third message digest algorithm created by Rivest.[23]
  • How MD5 works The MD5 message digest hashing algorithm processes data in 512-bit blocks, broken down into 16 words composed of 32 bits each.[23]
  • The final value computed from the last block becomes the MD5 digest for that block.[23]
  • The MD5 message-digest algorithm is a widely used hash function producing a 128-bit hash value.[24]
  • Although MD5 was initially designed to be used as a cryptographic hash function, it has been found to suffer from extensive vulnerabilities.[24]
  • The weaknesses of MD5 have been exploited in the field, most infamously by the Flame malware in 2012.[24]
  • MD5 is one in a series of message digest algorithms designed by Professor Ronald Rivest of MIT (Rivest, 1992).[24]
  • var fs = require ( ' fs ' ) ; var md5 = require ( ' md5 ' ) ; fs .[25]
  • Before version 2.0.0 there were two packages called md5 on npm, one lowercase, one uppercase (the one you're looking at).[25]
  • As of version 2.0.0, all new versions of this module will go to lowercase md5 on npm.[25]
  • This simple tool computes the MD5 hash of a string.[26]
  • As a reminder, MD5 is not a cryptographically secure hashing algorithm.[26]
  • Hash computing the MD5 checksum.[27]
  • An MD5 hash is created by taking a string of an any length and encoding it into a 128-bit fingerprint.[28]
  • MD5 hashes are also used to ensure the data integrity of files.[28]
  • The driver compiles for MD5 by default but can compile for MD2 or MD4 if the symbol MD is defined on the C compiler command line as 2 or 4.[29]
