Question

I want to save email accounts and passwords, which I will have previously encrypted with an algorithm. They need to be saved and read as binaries, with fwite and fread. What I want, is to be able to know if it’s a pass or an email account, saving it between < e > < e > and < u > < u >

For example:

<e> !"§(!"$)Asdn12§(!"§UASD <e>
<u> !"§()!="§ksd!"§KM!"§lkm12 <u>
<e> !"§KMK!M"§asd9i1ikm23ß0 <e>
<u> l,1ö2l3!"§)IQASD=K!"E <u>

how do you suggest should I read the file as binary but be also able to parse it.

Those emails and passes are read by another prog which performs some tasks with them.

Answer 1

If usernames and passwords are always paired I suggest you store the length (in number of bytes) before each username and before each password. This way you can read the length (say a 4 byte integer) and know how long the next username / password record will be. You can then repeat this without worrying about searching for tags that could occur within a username or password.
