Given that it matches the exact length of an MD5 hash, it is highly probable that this is an MD5 checksum or digest. 9d91003d4080b03d40742c819ea5228e

MD5 (Message Digest Algorithm 5) is a widely used cryptographic hash function that produces a 128-bit hash value. It is commonly used to verify data integrity (e.g., file downloads) and to store passwords (though now considered insecure for that purpose due to collision vulnerabilities). Any change in the input, even a single character, produces a drastically different hash. You can use the built-in Command Prompt

Hexadecimal strings like 9d91003d4080b03d40742c819ea5228e are commonly used as hash values or unique identifiers in computer science and information technology. Hash values are generated through hash functions, which take input data of any size and produce a fixed-size string of characters, known as a message digest or digital fingerprint. This process is one-way, meaning it's computationally infeasible to retrieve the original data from the hash value. It is commonly used to verify data integrity (e
