Double and wrong entry in ZIP
This is extremely handy! I'm going to use it in my project. I will credit you however you want; I intend to mention you/link to this gist in the README.md by default. Let me know.
Double and wrong entry in ZIP
29,152 should be 29152 to parse correctly for the ZIP entry.
@hyperreal-gopher Hi! Thanks for the report, I updated the gist, please let me know if you found any other issues!
And as for the credit, it doesn't need to be on the README put it wherever it feels right, I'd personally put the link as a comment in the source code where I'm loading the file, but it's me :)
And have a great time working on your awesome project!
On some sources, offsets are given in hex. In this case, offsets are in decimal. Maybe a comment making it explicit would be a improvement for this useful resource.
Hi @qti3e
I found there are some repeats in signs , such as jpg, where 0,FFD8 repeat 4 times.
"jpg": {
"signs": [
"0,FFD8",
"0,FFD8",
"0,FFD8",
"0,FFD8"
],
"mime": "image/jpeg"
},
Hey! This is cool! I was about to start putting something like this together based on https://en.wikipedia.org/wiki/List_of_file_signatures. I did notice there are some more signatures on the wikipedia article that are not on https://www.garykessler.net/library/file_sigs.html
For example, two alternative signatures for mp3 of FF F2 and FF F3, so I think "mp3" could be extended to:
"mp3": {
"signs": [
"0,494433",
"0,FFFB",
"0,FFF2",
"0,FFF3"
],
"mime": "audio/mpeg"
},
Thanks for cross-referencing these!
for eml I have also found: "Return-path: " in addition to "Return-Path: "
"eml": {
"signs": [
"0,46726F6D3A20",
"0,52657475726E2D506174683A20",
"0,52657475726E2D706174683A20",
"0,582D"
],
"mime": "message/rfc822"
},
Thanks. This is really cool. I am also using this in my project now. I will credit you in my code and readme.md - link to this gist. Thanks again
@diegocr thanks! fixed :)
