A security toolkit letting even less experienced programmers add encryption and authentication services to their apps, features that are becoming indispensable. The library hides low-level details of security from developers. It supports a variety of algorithms for symmetric/asymmetric encryption, authentication, and hashing. The library is free for non-commercial/shareware projects. It is written in C. ActiveX and C++ wrappers are available.

Visual MD5 is a freeware for you to get MD5 checksum of a file. It's a Windows GUI application, which is easy to use and free to distribute!

Fast, highly optimized implementation of hash and checksum algorithms: MD2, MD4, MD5, SHA-1, SHA-2(256,384,512), RIPEMD(128,160,256,320), PANAMA, TIGER, CRC-32, CRC-16, CRC-CCITT, ADLER32. The library allows to calculate hashes (message digests), checksums and HMACs for files, memory blocks, strings, streaming data. Has no external dependencies such as MFC DLL, COM/DCOM or other component. The help file has examples in Visual Basic(VB), C, C++.

MD5 Password is a password recovery tool that can recover a password if you know its MD5 hash. MD5 Password features highly configurable and fast recovery engine that can process up to 32,000 hashes simultaneously. Brute-Force Attack, Dictionary Attack, Hybrid Dictionary Attack and Smart Force Attack are supported. The support for the distributed recovery technology allows you to utilize the power of multiple computers.

MD5 Checksum Verifier is files integrity checker based on the time proven MD5 algorithms. With it you can easily create checksums of files and verify their integrity in the future. The operation is very easy, just two steps, make check file and verify check file.

Iside compares files and folders by computing their hash code (MD5,SHA1,...). Right click on a file, select Copy and by right clicking on another file you will discover if they are equal. Includes file comparison, hash displaying tool plus a complete folder comparison tool.
The hash functions allow to determine if two files are different even if their size is the same.
Ideal tool for configuration managers, programmers, deployers.

The Hyper Hasher Suite will fulfill all your file hashing needs. Hyper Hasher allows you to calculate 26 different hash/checksum and HMAC values for any file on your system, while the HashFile utility adds support for MD5 & SFV file creation and verification. These tools feature advanced options including a unique customizable interface, configuration saving, optional windows shell integration, Pentium 4 optimizations for speed, and much more!

HashMyFiles is small utility that allows you to calculate the MD5 and SHA1 hashes of one or more files in your system. You can easily copy the MD5/SHA1 hashes list into the clipboard, or save them into text/html/xml file.
HashMyFiles can also be launched from the context menu of Windows Explorer, and display the MD5/SHA1 hashes of the selected file or folder.

Free, fast calculator to compute hash, checksum, HMAC values for file, text and hex string. Supports popular message digest and check sum algorithms: MD2,MD4,MD5, SHA1,SHA2, RIPEMD160,PANAMA,TIGER, CRC32,ADLER32, and the hash used in eMule/eDonkey (eDonkey2000,ed2k). With this tool you can test for corruption FTP download/upload transfers, compare music,audio,video,game,image files, verify a CD, perform checking of mp3,mpeg,vcd,iso,zip downloads.

Simple utility to create checksum files based on the MD5 hash routine. Recursively scans a selected folder and creates the checkfile data which can then be loaded in for testing to determine if the files have changed at all. Great for putting in the root folder of a CD-ROM to make sure the disc isn't defective when it is burned or mass produced.

The DNS Library is a COM object that makes dynamic DNS updates to BIND, Microsoft and other RFC-2136-compatible DNS servers possible from any scripting languages in an easy way. The library supports the following record types: A, MX, SRV, NS, CNAME, PTR, TXT. The library implements 5 components: DnsLibrary.Server, DnsLibrary.Resolver, DnsLibrary.Authentication, DnsLibrary.ResourceRecord, DnsLibrary.ResourceRecordSet. Secure updates supported.

Comprehensive SFV and MD5 checksum utility for Windows. The handy and fast utility for protecting the integrity of files. It will allow you to verify the accuracy of your data after you burn a CD or transfer a files over a network. Adding an little checksum file to your data files will allow in further easily to verify their integrity at any time. Uses checksum files fully compatible with popular md5sum utility for MD5 and SFV for CRC32.

Too many internet logins? Use AMUST 1-Login and be secure!
AMUSt 1-Login allows a user to securely login into multiple web sites by signing to 1-Login only once. It organizes users? Internet accounts into secure bookmarks and provides a user with automatic "1-click" secure Internet logins. Unlike other password managers 1-Login does not employ a password database and does not store user?s passwords, even in the encrypted form.

This tool can generate a TSIG key value (base64) for you very easily. The key value complies with RFC2845. Secret Key Transaction Authentication for DNS (TSIG) is a secure method of authenticating clients making dynamic DNS update requests. The client application and the DNS server share a secret key value which is used to sign (HMAC-MD5) each update request. You can think of the key name as a user ID, and the key value as a password.
