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:
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.
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.
