Please see http://www.mathworks.com/matlabcentral/answers/9848-how-to-decrypt-a-pcode

ps: looks like you might have been trying to do the same thing as this long ago poster

thank u sir i am working on finger print recognization ,ai have to find centre point and crop in ,were do i get these codes can u help

[Walter Roberson]

I have never worked with finger print recognition, so I do not know of any sources. As you know what it is you want to do, you would be in a better position to Google for the information than I would be.

@Walter: I'm amused about the last sentence.

Answer 2

Hi may I know how to convert .p file to .m file extension ? I'm a student and I beg for your help .. I really need your help :(

[Walter Roberson]

You get a job with Mathworks and work with their team to write a tool to reverse engineer .p files into m code.

There has been speculation over the years that Mathworks Consulting probably has access to such a tool already, but I never bothered to ask them. You can be fairly certain that if they do have such a tool that they would require proof that you had the legal rights to the source code. (If you are trying get m file source for fingerprint recognition .p file then you are unlikely to be able to convince them that you have the necessary legal rights.)

[Jan]

@Margie: P coding is used to conceal the contents of an M file. Then converting it back to readable code is not wanted by the author. Note that the question has been answered already.

Sorry , But is Logic Matlab add this features "Crypt open source code (.m => .p)" like a sécruté for dévlopper to protect their work

[Bruno Luong]

Why not? They (TMW) are probably the first one to want/need it.

And why you think MATLAB program would be an open source? Most of them are but not all.

[Darin Salhi]

Yes , but in some cases , like a freelance job , or contrat job , developer need to decrypt the code.

[Walter Roberson]

Developers who have legal rights to reverse engineer the .p code typically already have access to the original source.

There are some exceptions:

• sometimes companies lose their source code but still have the .p around and later need to get back to source
• in some situations involving one company purchasing another company, there might be legal rights to the intellectual property but the original code might not be available
• in some countries, reverse engineering is legal, at least within some contexts. For example in some countries, security researchers have the legal right to reverse engineer code to attempt to find security problems. In some countries, people with disabilities have rights to adapt software to make it usable for them.

@Boukamcha Hamdi: I'm not sure if your answer is clear. Do you mean, that it is a useful procedure to encrypt readable M files to not readable P files? If you mean this, I do agree. Then it is wanted, that the decryption is not possible for other users.
