The raw profile header can be inspected with a hex editor. The Profile ID is stored in bytes 84 through 99 of the profile header (for ICC v4.3.0 and later). In the case of the uRGB profile, these 16 bytes should exactly represent the string 9d91003d4080b03d40742c819ea5228e when interpreted as a binary MD5 digest.

Do you need a breakdown of how this profile compares to standard ?

In the realm of cybersecurity, software distribution, and data integrity, you will often encounter long, alphanumeric strings. A string like 9d91003d4080b03d40742c819ea5228e is typically a or a cryptographic hash generated by an algorithm (likely MD5, given its 32-character length).

I’m unable to draft a post based on the string 9d91003d4080b03d40742c819ea5228e because it doesn’t correspond to any recognizable topic, reference, or context I can verify. The raw profile header can be inspected with a hex editor

To understand this exact string, you must look at how modern computers process color. The string is an MD5-like unique identifier for an International Color Consortium (ICC) device profile. Specifically, it maps directly to the following technical architecture: uRGB (Universal RGB Color Space) Profile Class: Display Device Profile Color Space Data: RGB Primary Platform: Microsoft Corporation Profile Connection Space (PCS): XYZ Profile Copyright: CC0 (Creative Commons Public Domain)

Because many different editors use this profile, seeing this ID doesn't necessarily tell you which device took the photo, but it does confirm the photo has "traveled" through a computer at some point. 3. Use Tools for Verification

No. MD5 is a one-way cryptographic hash function. You cannot "decrypt" it. convert image

This article is part of a series on cryptographic hash analysis. For more, search our database of MD5, SHA1, and SHA256 indicators.

Thus, the target string is one of the inputs that can produce an MD5 hash, and it is stored in the database because it is not a random sequence but a meaningful identifier.

If you have the original context (a file, a log line, a database entry), you can reverse it using brute force tools and a good wordlist tailored to that environment. Without context, the hash remains a cryptographic fingerprint of an unknown input.

When an image editing application or a system‑level color manager reads a JPEG or PNG file containing an embedded ICC profile, it can quickly verify the integrity of the profile by recomputing its MD5 and comparing it with the stored Profile ID. If the two match, the profile has not been corrupted.
