SB-MD5 Checksum Calculator is a tool to calculate and compare the MD5 checksum of files. The MD5 checksum is used worldwide for checking the integrity of files. The MD5 checksum has been around for over 10 years. It was designed by professor Ronald L Rivest in 1991. The MD5 algorithm has been used by many security applications and integrity control applications since it was published as an internet standard (RFC-1321) in 1992. SB-MD5 Checksum Calculator is a tool to calculate and compare the MD5 checksum of files. The MD5 (Messege-Digest Algorithm 5) is a widely used cryptographic hash function with 128-bit hash value. The MD5 hash is like a fingerprint of a file. Features •Calculate MD5 checksum of a file. •Compare MD5 checksum of two files. •Copy MD5 hash to Windows clipboard. •Compare value from the clipboard with MD5 checksum of a file. •It is free.
