The main interface and the options available
The main window of HashCalc 2.02 has four sections: Input Data, Data Format, Hash Algorithm, and Output Format.
The Input Data section allows you to enter or select the data that you want to calculate hashes, checksums, or HMACs for. You can either type or paste a text string or a hex string, or browse for a file on your computer. You can also drag-and-drop a file or text into this section.
The Data Format section allows you to choose the format of your input data. You can choose from three options: File, Text String, or Hex String. Depending on your choice, the Input Data section will change accordingly.
The Hash Algorithm section allows you to choose the hash or checksum algorithm that you want to use for your calculations. You can choose from 13 options: MD2, MD4, MD5, SHA1, SHA256, SHA384, SHA512, RIPEMD160, PANAMA, TIGER, ADLER32, CRC32, and eDonkey/eMule.
The Output Format section allows you to choose the format of your output data. You can choose from three options: Uppercase Hexadecimal, Lowercase Hexadecimal, or Base64. Depending on your choice, the output data will be displayed in different formats.
The two modes of calculations: Hash/Checksum and HMAC
HashCalc 2.02 has two modes of calculations: Hash/Checksum and HMAC.
The Hash/Checksum mode allows you to compute hashes or checksums for your input data using any of the 13 algorithms available. This mode is useful for verifying file integrity, generating passwords, encrypting data, or identifying duplicate files.
The HMAC mode allows you to compute HMACs (Hash-based Message Authentication Codes) for your input data using any of the 13 algorithms available and a secret key that you provide. This mode is useful for authenticating messages, ensuring data integrity, or preventing tampering.
To switch between the two modes, you can use the radio buttons at the bottom of the window. Depending on your choice, you will see an additional field for entering the secret key in HMAC mode.
The three input data formats: files, text strings, and hex strings
HashCalc 2.02 supports three input data formats: files, text strings, and hex strings.
Files are any type of files that you have on your computer or a removable drive. You can select a file by clicking on the browse button (...) next to the Input Data field or by dragging-and-dropping a file into this field. The software will automatically detect the size and name of the file and display them below the field.
Text strings are any type of texts that you can type or paste into the Input Data field. The software will automatically detect the length and encoding of the text and display them below the field.
Hex strings are any type of hexadecimal values that you can type or paste into the Input Data field. The software will automatically detect the length and validity of the hex string and display them below the field.
The supported hash and checksum algorithmsThe supported hash and checksum algorithms
HashCalc 2.02 supports 13 hash and checksum algorithms that are widely used and recognized in the fields of cryptography, security, and data integrity. Here is a brief description of each algorithm and its output length:
Algorithm
Description
Output Length
MD2
A message-digest algorithm designed by Ronald Rivest in 1989. It is optimized for 8-bit machines and is considered insecure by today's standards.
128 bits
MD4
A message-digest algorithm designed by Ronald Rivest in 1990. It is faster than MD2 but has several weaknesses that make it vulnerable to attacks.
128 bits
MD5
A message-digest algorithm designed by Ronald Rivest in 1991. It is widely used for various purposes but has been proven to be susceptible to collisions and other attacks.
128 bits
SHA1
A secure hash algorithm designed by the NSA in 1995. It is based on the SHA-0 algorithm but has some modifications to improve its security. However, it is no longer considered secure due to the discovery of collisions.
160 bits
SHA256
A secure hash algorithm designed by the NSA in 2001. It is part of the SHA-2 family of algorithms and produces a longer output than SHA1 to resist brute-force attacks.
256 bits
SHA384
A secure hash algorithm designed by the NSA in 2001. It is part of the SHA-2 family of algorithms and produces a longer output than SHA256 to resist brute-force attacks.
384 bits
SHA512
A secure hash algorithm designed by the NSA in 2001. It is part of the SHA-2 family of algorithms and produces a longer output than SHA384 to resist brute-force attacks.
512 bits
RIPEMD160
A hash function developed by Hans Dobbertin, Antoon Bosselaers, and Bart Preneel in 1996. It is based on the RIPEMD algorithm but has some improvements to increase its security.
160 bits
PANAMAA hash function designed by Joan Daemen and Craig Clapp in 1998. It uses a stream cipher to generate a variable-length output that can be truncated to any desired length.Variable (up to 256 bits)TIGERA hash function designed by Ross Anderson and Eli Biham in 1995. It is optimized for 64-bit machines and has a fast and simple structure.192 bitsADLER32A checksum algorithm designed by Mark Adler in 1995. It is a variant of the Fletcher checksum and is faster than CRC32 but less reliable.32 bitsCRC32A cyclic redundancy check algorithm that is widely used for error detection in data transmission and storage. It is based on polynomial arithmetic and has a high detection rate for common errors.32 bitseDonkey/eMuleA custom hash algorithm that is used in the eDonkey and eMule peer-to-peer file sharing applications. It is based on the MD4 algorithm but has some modifications to suit the application's needs.128 bitsYou can select any of these algorithms from the drop-down menu in the Hash Algorithm section of HashCalc 2.02.
How to compare hashes and verify file integrity
One of the main uses of hashes and checksums is to verify the integrity of files or data. By comparing the hashes or checksums of two files or data, you can check if they are identical or not. This can help you detect any corruption, modification, or tampering that might have occurred during transmission or storage.
To compare hashes or checksums using HashCalc 2.02, follow these steps:
- Select the File option from the Data Format section - Browse for the first file that you want to compare and select it in the Input Data field - Choose the hash or checksum algorithm that you want to use from the Hash Algorithm section - Click on the Calculate button to compute the hash or checksum of the first file - Copy the result from the Output Data field by clicking on the Copy button - Browse for the second file that you want to compare and select it in the Input Data field - Click on the Calculate button to compute the hash or checksum of the second file - Paste the result from the first file into the Compare With field by clicking on the Paste button - Click on the Compare button to compare the two hashes or checksums - You will see a message below the Compare With field that indicates whether the two hashes or checksums match or not Alternatively, you can also compare hashes or checksums with a reference value that you have obtained from another source, such as a website, a document, or a person. To do this, follow these steps:
- Select the File option from the Data Format section - Browse for the file that you want to verify and select it in the Input Data field - Choose the hash or checksum algorithm that you want to use from the Hash Algorithm section - Click on the Calculate button to compute the hash or checksum of the file - Copy the reference value that you have obtained from another source and paste it into the Compare With field - Click on the Compare button to compare the hash or checksum of the file with the reference value - You will see a message below the Compare With field that indicates whether the hash or checksum of the file matches with the reference value or not Conclusion
