Md5: 0a1de734371e658703bf4d2e9a3d0492 hash digest (reversed, unhashed, decoded, decrypted)
MD5 (128 bit). The MD5 message-digest algorithm is a widely used cryptographic hash function producing a 128-bit (16-byte) hash value, typically expressed as a 32 digit hexadecimal number. 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.
MD5 is one in a series of message digest algorithms designed by Professor Ronald Rivest of MIT (Rivest, 1992). When analytic work indicated that MD5's predecessor MD4 was likely to be insecure, MD5 was designed in 1991 to be a secure replacement. (Weaknesses were indeed later found in MD4 by Hans Dobbertin.)
