About MD4 hash algorithm:

The MD4 Message-Digest 4 Algorithm is a cryptographic hash function developed by Ronald Rivest in the early 1990s. The digest length is 128 bits, 32 characters long. The algorithm has influenced algorithms, such as the MD5, SHA-1 and RIPEMD algorithms. The initial character "MD" stands for "Message Digest."

MD4 has not been considered secured as one can easily attack Md4 with collisions, in a few milliseconds. MD4 with few differences is used for digest on Microsoft products. The first full collision attack against MD4 was done in 1995 when the 1st successful collision attack against it was performed by one Hans Dobbertin and several newer attacks have been done since then. We should not use Md4 as a cryptographic function in our site to store critical data, since it's very easy to decrypt. We help you to allow decrypt your md4 hashes in to plan text.

With our online tool you can encrypt any simple text of length 500 and you can also descript any hash code for free.
