Understanding uRGB and the Profile ID: 9d91003d4080b03d40742c819ea5228e

While the string itself is not secret, the algorithms that generate it (MD5 and SHA‑1) have known security weaknesses.

The string 9d91003d4080b03d40742c819ea5228e is a 32‑character hexadecimal value. On first glance it resembles an MD5 or SHA‑1 cryptographic hash – a digital fingerprint that uniquely identifies an input of any length and returns a fixed‑size output. Like the MD5 hash of the word “password” yields 5f4dcc3b5aa765d61d8327deb882cf99 , this hash may be used to validate file integrity, encrypt sensitive data, or generate unique identifiers. However, a deeper investigation reveals that this sequence is not merely a hash of a user password or a file checksum; it functions as a Profile ID inside an ICC (International Color Consortium) color profile.

Ever wondered what that "9d91003d..." ID in your image metadata means? If you’re digging into your EXIF data with tools like 9d91003d4080b03d40742c819ea5228e full

: The profile is associated with Little CMS (an open-source color management engine) and identifies itself with the "hand" creator code and "saws" manufacturer code in its internal metadata.

You can crack it using:

The string 9d91003d4080b03d40742c819ea5228e appears to be a unique digital identifier, most likely an MD5 hash. In the world of data management and cybersecurity, these 32-character hexadecimal codes serve as digital fingerprints for files, passwords, and specific pieces of data. When users search for this specific hash followed by the word full, they are typically looking for the original content that matches this signature or a complete decryption of the underlying data.

The string appears under the description uRGB . In the color management world, uRGB is like sRGB or Adobe RGB; rather, it is a label for a compact version of the sRGB color space as defined in the GitHub project Compact‑ICC‑Profiles by user saucecontrol .

An ICC profile solves this problem. By embedding a standard profile into an image file, you are providing a precise mathematical description of that image's colors. The rendering device (like a monitor) can read this profile and then use its own internal profiles to translate the image's colors to its own capabilities, creating a consistent visual experience. If you’re digging into your EXIF data with

When you see 9d91003d4080b03d40742c819ea5228e in the metadata (specifically, the EXIF data) of digital images, it is labeled as Profile ID . This section of the metadata contains a wealth of technical information about a color profile:

The specific string is the for the uRGB profile creator, often generated by the Little CMS (lcms) color management engine. How to tell if same device was used for different images

When an image is modified in editing programs like Adobe Photoshop or GIMP, the editing suite usually overwrites or appends its own color profile configurations. In professional media verification, identifying an unexpected color profile acts as an immediate indicator of a non-original source.
