![]() The origin of the idea is to produce unique hashes, but it is proved that it has collusions which makes it vulnerable. The following image shows how MD5 works it produces a unique hash with same length for different strings that has different lengths. If it is a complex one, it may be still cracked with super computers with trial and error. If the text that is decrypted is a common phrase or a short string, it takes only seconds to decrypt it. Most developers still used it in their databases to store sensitive information like passwords or user information, but it can be cracked easily. One usage purpose is to be used as checksum for data integrity. Even MD5 has such vulnerabilities, it is still used widely. Also, with the advances in computer technology and hardware, it becomes easier to crack MD5 hashes. In recent years, SHA256 or SHA512 are used instead of MD5 since it has vulnerabilities and some issues about collusion that means 2 different inputs creates the same hash. MD5 is created for cryptographic purposes in 1991. It is an irreversible function, that means, you can create an MD5 hash with a function directly, but you can't reverse it, in other words, you can't decrypt it with a function. MD5 stands for "Message-Digest algorithm 5". No matter how long the input string is, it generates a unique output. MD5 is a hashing function that creates a unique 128-bit hash with 32 characters long for every string. In other words, this tool is a combination of MD5 hash generator and MD5 decrypter. MD5 Encrypt/Decrypt is a free online tool for generating MD5 hashes from strings and decrypting MD5 hashes to strings.
