Advanced CheckSum Verifier - MD5 and SFV checksum utility for Windows

Secure Hash Algorithm

SHA (Secure Hash Algorithm) was designed by the National Security Agency (NSA) in 1993 as the algorithm of the Secure Hash Standard (SHS, FIPS 180). It was modeled after MD4 with additional improvements. An undisclosed security problem prompted the NSA to release an improved SHA-1 in 1995. Florent Chabaud and Antoine Joux later discovered a differential collision attack against SHA in 1998. There are currently no known cryptographic attacks against SHA-1.

It is also described in the ANSI X9.30 (part 2) standard. SHA-1 produces a 160-bit (20 byte) message digest. Although slower than MD5, this larger digest size makes it stronger against brute force attacks.

What is Advanced CheckSum Verifier (ACSV)?

The Advanced CheckSum Verifier is an small, GUI-driven Windows checksum utility intended for creation and verification the checksum files both in SFV and MD5SUM formats. ACSV will help Windows users to protect the integrity of their files by using the CRC32 or MD5 checksum calculation algorithms.

ACSV will useful when necessary to verify the accuracy of files burned to CD-R(W) or transmitted over network, or for files comparison, or for detection of corrupted or tampered files. Adding an little checksum file to your data files will allow easily to verify their integrity at any time in further and allow you to reveal what files has been changed.

ACSV is especially effective if you have many files, many subdirectories, or both. And it's extremely fast and lightweight.

ACSV uses checksum files fully compatible with popular md5 utility for MD5 and SFV (Simple File Verification) for CRC32.
