Internet has made file sharing tenfold easier. We can easily share files via various services available on the internet. But with this, file integrity has become a serious issue. Every other day, we hear the news of some hacker group compromising a major company's confidential data. Sometimes, they don’t use their own computers to perform these malicious activities, but instead employ backdoors to enter the systems of unsuspecting, unguarded internet users and gain access to their systems. Checking the integrity of files is very important if you don’t want your computer to get infected with viruses and malware. Sometimes, hackers modify the contents of a downloadable zip, which can even grant them complete remote access to your system. To fight this, developers usually provide a hash value along with the download link, which works as a proof for originality of the file. The integrity of the downloaded file is checked by generating a hash value of your own, and comparing with the one provided by the developer. The hash values can be calculated and compared using a number of tools available on internet. HashMyFiles is one such portable utility that allows you to quickly calculate checksum values of one or multiple files located on your hard drive and save the resulting list as HTML, XML or text.

Encrypting files to prevent unauthorized access and external data theft attacks can be achieved using a number of file encryption software, which allow users to choose an encryption algorithm and encrypt  key to secure the specified files. Like Mac OS X, Windows 7 also enables you to encrypt files across the disk partitions to ensure data safety, and also to restrict others from reading/writing the data. BitLocker and TrueCrypt are probably the best tools available for this very purpose. Although one can create encrypted containers for holding specified files and folders using Truecrypt, it requires following quite a lengthy wizard and configuring complex settings to encrypt a set of files. Simialrly, Windows 7 built-in BitLocker allows encrypting the entire disk, but if you’re encrypting a large disk volume, it may take hours to complete the encryption process. If you’re looking for a super powerful data encryption tool that can encrypt and decrypt specified files with a click, WinAES is a solid pick. Read past the jump for details. Read More

Checking the integrity of files is very important if you don’t want your computer to get infected with viruses and malware. Sometimes, hackers modify the contents of a downloadable zip, which can even result in granting them remote access to your system. While downloading various software, you might have noticed that developers usually provide hash values of their files computed according to different checksum protocols. This enabls you to verify the file integrity of the downloaded content. Previously, we have covered a lot of Windows application for calculating hash values to verify file integrity, including Digesec Hashing Utility, inCrypto and Md5Checker, as well as some shell extensions, such as Shell Extensions like HashTab and FilePropsMan. These programs let you calculate and compare hash values, allowing you to keep you computer safe from infected files. Today, we have another tool to add to the list of hash generators, called MD5 Checksum Tool. It allows you to scan all files of a folder with recursive support, and creates a report with the checksum values of all files along with their file names and sizes. Moreover, it allows you to compare two files against each other, and compare an MD5 hash value against a file to know if it has been modified in any way. More on MD5 Checksum Tool after the break.

Checking the integrity of files is very important if you don’t want your computer to get infected with viruses and malware. Sometimes, hackers modify the contents of a downloadable zip, which can sometimes even grant them remote access to your system. Developers usually provide hash values of downloadable files in different checksum protocols, enabling you to verify the file integrity of downloaded content. You can download the file, generate its hash value, and compare it with the one given on the developer's website. If you are looking for a good utility to generate and compare hash values of files, check out Md5Checker. It is one such portable application that allows you to calculate and verify hash values for multiple files at a time. After calculating the Md5, you can either compare it manually, or save it to match it with the hash value of the same file at a later time. It can also be used to verify if the file has been tampered with in any way. Read More

Encrypting a file allows you to send it over the internet safely without worrying about its contents being read, or used by someone who is not intended to read them. for instance, a file that you upload on the internet might get hacked by someone with malicious intentions. If  the file contains sensitive information, that can create a lot of trouble for you. Hashing a file, on the other hand, can be used to make sure that the file you downloaded is exactly the one that was uploaded by the author and not a file modified by a hacker. Developers often post the hash value along with the uploaded file, so that anyone downloading it can be sure that it is the same file that was originally uploaded by the author. Previously, we have covered a lot of tools, such as SFV Ninja, a portable hash value generator, that can be used to generate and compare hash values of files in order to verify their integrity. We have also covered some text encryption tools, like scrambled-egg, an open source application that allows encrypting plain text messages and files using custom encryption algorithms. Combining the features of both these applications, today we have a new tool for you called inCrypto. It is a multipurpose portable tool that lets you perform, both encryption and encoding, from a unified interface. The application supports Base64 and AES text encoding and encryption methods, while MD5, SHA-1 and SHA-256 FIle Hash values can be used to generate hash values of files.

Hash values are used to verify the integrity of files, and zip archives. If the contents of the file, or a zip archive change, its hash value will also change. So, if the file has been tampered in any way, it can be checked by generating its hash value and comparing it with the value of the original file. Previously, we have covered, both tools, as well as extensions that allow users to generate and compare hash values of files to verify their integrity. Applications like SFV Ninja and HashSlash let you generate and verify hash values, while Shell Extensions such as HashTab and FilePropsMan adds a tab containing file hash information and verification in the properties of files. Digesec Hasing Utility is a hash utility that lets you generate and verify hash values of file, as well as text. It can be used to confirm the authenticity of a file and hash passwords. The application supports a lot of hashing algorithms such as ADLER, CRC32, MD5, SHA-1, SHA-256, TIGER etc. Read More

Hash values let you check if a file has been tampered with in any way or not. While downloading a file from the internet, you might have noticed that sometimes, a string of numbers and alphabets is written beside, over or under the download link of the file, that is the hash value of the file generated by the developer who uploaded the file. In order to check if a hacker has accessed the file and changed the content to suit his own malicious needs, after downloading the file, you can generate the hash value on your own and match it with the one provided by the developer in order to check for any discrepancies. Yesterday, I covered FilePropsMan, a Windows Explorer Shell Extension that adds extended version and file hash information in the Windows Explorer File Properties menu. The application lets you generate values for CRC32, MD5 and SHA-1 checksum protocols. If you are looking for an application that just calculates the hash values, HashTab is worth a look. It adds a new tab in File Properties and automatically calculates file hashes for different protocols such as CRC32, MD4, MD5, SHA-1, SHA-256, Tiger, Whirlpool etc. Moreover, it lets you compare a file to confirm file integrity.

The massive world of internet contains tons of applications, tools and software. Sometimes, it may happen that you are not be able to find which one is a fabricated tool, and which comes straight from the developer. Developers mostly generate the Hash of a download bundle, which is quite useful in checking the file integrity of something that you are about to download. Previously, we have covered various applications that allow you to generate and check has values of files, such as HashSlash, a Windows Explorer Shell Extension that adds extended version and file hash information in the Windows Explorer File Properties menu, and SFV Ninja, a portable hash value verification tool, which supports SFV, MD5 and SHA-1 checksum algorithms. Today, we have another tool for you that allows you to view the hash values of files generated according to 3 different algorithms. FilePropsMan is a Windows Explorer shell extension that adds two tabs, namely Extended Version Information and File Hash Information, to the Windows Explorer File Properties menu. It lets you view detailed version information about the file included by the developer, as well as generating CRC32, MD5 and SHA-1 Hash codes to verify against the ones provided by the developer.

Rainbow tables are pre-computed tables, used for reversing cryptographic hash functions, which are often used for cracking password hashes. Computers which rely on password authentication require a mechanism to determine if the entered password is correct. One can store a cryptographic hash of the password to protect the stored information because such hashes are difficult to reverse. OSForensics enables you to use Rainbow Tables to retrieve passwords, provided you have the hash of that password. The use of rainbow tables serve as a time-memory trade off in the decryption of a hash. With OSForensics you can also recoverybrowser passwords, aggregate and organize results and case items, analyze systems main memory, CPU, USB and hard drive information, uncover the user actions performed recently on the system, create an index of the files on a hard disk, look up files quicker than Windows default functionality, and much more. The main interface contains multiple tabs and sub-categories which contain options to perform the aforementioned tasks. Read More
