**different hashes ? [#w61449b7]
>[[LWS]] (2025-06-10 (Tue) 08:39:41)~
~
#FuguIta~
~
Hi, first of all I would like to give you my warmest compliments for this fantastic project. It is really very well done and extremely flexible.~
I approached your project because I wanted to do a security check on my openbsd desktop. I wanted to check the base system and specifically everything in /usr/X11R6 i.e. the graphics server infrastructure. What I noticed, however, is an inconsistency between the hashes of my machine and some fuguita binaries and libraries. In fact, I assumed that the fuguita base system was taken from the openbsd installation iso. So assuming this and given that there was a hash variation I came to the wrong conclusion that there were indicators of compromise on my PC. But then I had doubts so I downloaded the openbsd 77 iso and rechecked the hashes which instead were correct. The ones that were not correct were those of fuguita. So I would like to ask you if these files were compiled by you and why only some are different and while others are not. Thank you very much and best wishes for fuguita.~

- Hi, and thank you very much for your kind words and your thoughtful question.~
To clarify: all binaries in FuguIta are built entirely from source using the procedures described in the OpenBSD manual page [[release(8)>man:release]]. That means the base system in #FuguIta is not taken directly from the official OpenBSD installation ISO, but instead is fully rebuilt by myself from the same source code.~
Therefore, it is expected that the hash values of binaries and libraries in FuguIta may differ from those in the official release — even if the source code is identical.~
Interestingly, some hashes match while others do not. I do not know the precise reason for this, but possible factors might include:
--embedded timestamps or other non-deterministic metadata (so-called “magic numbers”),
--differences in environment during build time (e.g., order of linking),
--or perhaps effects from security features like ASLR (Address Space Layout Randomization) or similar mechanisms during or after compilation.
-Additionally, the OpenBSD official release remains unchanged during its lifecycle, except for syspatches. In contrast, FuguIta may undergo multiple CVS updates and full rebuilds of OpenBSD during the release cycle, whenever needed. This can naturally result in differences in the resulting binaries compared to the static official builds.~
That said, if you'd like to ensure maximum trust and reproducibility from a security standpoint, you’re more than welcome to rebuild your own version of FuguIta, following [[the method described in the FuguIta Guide>fge4:build_fuguita]]. This way, you can verify the entire build process yourself.~
Thanks again for your feedback and for using FuguIta!~

- Diese Konversation wurde mit Duck.ai unter Verwendung des Mistral Small 3-Modells von Mistral AI generiert. ==================== What is a Hash? Mistral Small 3: A hash is a fixed-size numeric value that is generated from a string of text using a hash function. Hash functions take an input (or 'message') and return a fixed-size string of bytes. The output is often represented as a hexadecimal number. Hashes are commonly used in various applications, including data integrity verification, cryptography, and data indexing. ### Key Properties of Hash Functions: 1. **Deterministic**: The same input will always produce the same hash output. 2. **Fixed Size**: Regardless of the size of the input, the hash output is always the same length. 3. **Efficient**: Hash functions are designed to be computationally efficient. 4. **Preimage Resistance**: Given a hash value, it should be computationally infeasible to find the original input. 5. **Second Preimage Resistance**: It should be computationally infeasible to find a different input that hashes to the same value as a given input. 6. **Collision Resistance**: It should be computationally infeasible to find two different inputs that hash to the same value. ### Common Hash Functions: - **MD5 (Message Digest Algorithm 5)**: A widely used hash function, but considered broken and unsuitable for further use. - **SHA-1 (Secure Hash Algorithm 1)**: Also considered broken and not suitable for further use. - **SHA-2 (Secure Hash Algorithm 2)**: A family of hash functions that includes SHA-256, SHA-384, and SHA-512. SHA-256 is commonly used in cryptographic applications. - **SHA-3 (Secure Hash Algorithm 3)**: The latest member of the Secure Hash Algorithm family, designed to be more secure and flexible. ### Example Use Cases: - **Data Integrity**: Hashes can be used to verify that data has not been tampered with. For example, downloading a file and comparing its hash to a known good hash can ensure the file has not been altered. - **Cryptography**: Hashes are used in various cryptographic protocols, such as digital signatures and password storage. - **Data Indexing**: Hashes can be used to quickly index and retrieve data in databases and other storage systems. ### Example in Python: Here's a simple example of how to generate a SHA-256 hash in Python: ```python import hashlib # Input string input_string = "Hello, World!" # Create a SHA-256 hash object hash_object = hashlib.sha256() # Update the hash object with the bytes of the input string hash_object.update(input_string.encode('utf-8')) # Get the hexadecimal representation of the hash hash_hex = hash_object.hexdigest() print("SHA-256 Hash:", hash_hex) ``` This code will output the SHA-256 hash of the string "Hello, World!". #FuguIta -- [[budlun]] &new{2025-06-12 (Thu) 00:23:08};
- There are several reasons why #FuguIta sometimes does a full build of the base OpeBSD.&br;One is to prevent any errata from being missed.&br;The other is to deal with the rare occasions when source code is modified in the -stable branch at a level that is not reflected in the errata.&br;Furthermore, FuguIta's update tool, fiupdate, differs from OpenBSD's syspatch in that it always overwrites the entire OS, including the kernel, so a full build ensures the integrity of the entire system.&br;Also, the kernel is always regenerated when a release is created, even if there are no changes to the kernel. This ensures that a randomly linked kernel is provided for each release. -- [[kaw]] &new{2025-06-13 (Fri) 10:12:27};
- Too bad, you don't say anything lws #FuguIta Are lws a juggler? -- [[budlun]] &new{2025-06-26 (Thu) 06:49:30};
- Whether or not LWS chooses to reply is entirely up to him. At #FuguIta BBS, both active participation and quiet observation are equally respected. -- [[kaw]] &new{2025-06-26 (Thu) 10:09:19};
- Thank you kaw for respecting my rights. #FuguIta -- [[budlun]] &new{2025-06-26 (Thu) 21:34:32};
- In this case a opinion and question of no equal rights? #FuguIta -- [[budlun]] &new{2025-06-26 (Thu) 21:44:11};
- What about passive participation and poignant observation? #FuguIta -- [[budlun]] &new{2025-06-26 (Thu) 22:10:33};

Hello kaw,~
~
I've been with #FuguIta for more than a quarter now.~
I love it, much more like OpenBSD.~
~
To you, dear kaw, I value you very much. I want to take this opportunity to appreciate your work very much. I can't even describe it, I have tried so much, but only with FuguIta my cognetive dessonance on the computer is finally over and using Fuguita is no longer a problem for me cognetively.~
~
For me, 4 points were decisive, which are well described in the FuguIta Guide.~
~
Although I had already worked a lot with Unix, I would never be so well without FuguIta.~
I am finally happy.~
I'm glad.~
Thank you very much kaw.~
Best regards budlun~
//
- Dear Budlun, I am very happy to hear that you are taking advantage of FuguIta. I am especially pleased to hear that the FuguIta Guide has contributed greatly to your use. It was worth the effort to write it. I hope you will continue to enjoy #FuguIta. -- [[kaw]] &new{2025-04-26 (Sat) 01:08:35};
