MD5 is a widely used cryptographic hash function, which produces a hash of 128 bit. In this article, we will see different approaches to create MD5 hashes using various Java libraries. MD5 Using MessageDigest Class. There is a hashing functionality in java.security.MessageDigest class. MD5 has been utilized in a wide variety of security applications. It is also commonly used to check data integrity. The 128-bit (16-byte) MD5 hashes (also termed message digests) are typically represented as a sequence of 32 hexadecimal digits. MD5 was designed by Ron Rivest in 1991 to replace an earlier hash function, MD4.

This MD5 hash generator is useful for encoding passwords, credit cards numbers and other sensitive date into MySQL, Postgress or other databases. PHP programmers, ASP programmers and anyone developing on MySQL, SQL, Postgress or similar should find this online tool an especially handy resource.

What is an MD5 hash?

An MD5 hash is created by taking a string of an any length and encoding it into a 128-bit fingerprint. Encoding the same string using the MD5 algorithm will always result in the same 128-bit hash output. MD5 hashes are commonly used with smaller strings when storing passwords, credit card numbers or other sensitive data in databases such as the popular MySQL. This tool provides a quick and easy way to encode an MD5 hash from a simple string of up to 256 characters in length.

MD5 hashes are also used to ensure the data integrity of files. Because the MD5 hash algorithm always produces the same output for the same given input, users can compare a hash of the source file with a newly created hash of the destination file to check that it is intact and unmodified.

An MD5 hash is NOT encryption. It is simply a fingerprint of the given input. However, it is a one-way transaction and as such it is almost impossible to reverse engineer an MD5 hash to retrieve the original string.

WinMD5Free

WinMD5Free is a tiny and fast utility to compute MD5 hash value for files. It works with Microsoft Windows 98, Me, 2000, XP, 2003, Vista and Windows 7/8/10.

As an Internet standard (RFC 1321), MD5 has been used in a wide variety of security applications, and is also commonly used to check the integrity of file, and verify download. WinMD5 is a small and easy tool to calculate md5 hash or checksum for different files (including files larger than 4 GB).

• Supports almost all Windows platforms including Microsoft Windows XP, Vista, Windows 7, 8, and Windows 10.
• Fast and multi-threaded. It can compute a 2 GB file less than 1 minute.
• Supports big files larger than 4 GB.
• Low resource usage. It uses less than 5 MB RAM.
• Don’t require .NET runtime installed. It is a standalone EXE file and the startup is speedy. There are MD5 tools for Windows on the market, but most of them requires .NET runtime and they may take a few seconds to start. This is also the reason I wrote the program.
• Supports “Drag & Drop”. You may either select a file, or drag and drop a file to the program window to get the MD5 hash value.
• Supports verification of original MD5 value and current MD5 value.
• Most important, it is FREE. No spyware or adware bundle.
• Small size, an effective and tiny tool for data security.
