 # Developer notes
 **Programming language:** TypeScript
+
 **Framework:** Electron (latest)
+
+## Encryption
+OffPass uses PGP in the background with symmetric encrpytion.
+
+### Passphrase
+The passphrase is the actual key which is used for encrpytion. But we don't use your entered master password directly. We hash it with `Argon2i` about 25 times. This gives use an output like this: `29dbf5392f13f36d7e9509b1a5c9add0d6a8e2625b5e84ab4d1df8da6063625d`.
+
+This value will be used as passphrase, not your plain password. The creation of this hash takes about **more then one second**. 
+
+Attackers are using password dictionaries with more then one million passwords. Creating such a hash for each password in there would take **millions of years**.
+
+## QR-Code schema
+An OffPass QR-Code must follow this data schema or else OffPass wouldn't be able to read it. **The following examples are data after decryption.**
+```
+name|password|email|website_url|(custom1)data1|(custom2)data2
+```
+Als Beispiel:
+```
+Main Steam Account|super_secret_example123|info@example.de|https://store.steampowered.com/login/|(2fa_backup)R1337
+
+ProtonMail|mail_pw123|klier.nicolas@protonmail.com||
+```
+These characters are reserved and cannot be used for any fields: `|%§`
+
+### Compression
+It is possible to compress QR-Codes. Instead of writing all data to the QR-Code you can write random strings (key) to it. OffPass itself holds a database of those random string and the corresponding encrypted value.
+
+The program generates a `session key` (length of 10 characters) which is unique for each QR-Code. This session key is stored on the QR-Code and is used to encrypt the raw values in database. So not even If someone stells your database he wouldn't be able to read your compressed strings.
+
+The compression key is stored like that: `§key`, the decryption key is stored like that: `%decryption_key%` always at the beginning.
+
+For example:
+```
+%session_key%§xa|passwords_not2134|email_too@example.com|§q|(§a)§gh|(uncompressed)value
+
+-> Google|passwords_not2134|email_either@example.com|https://accounts.google.com|(2fa_backup)245131,...|(uncompressed)value
+```
+
+This can has two advantages:
+* An attacker can't read compressed values (he would need the database)
+* You can get more data on one QR-Code
+
+But one disadvantage: 
+* **If you lose access to the compression database, you also lose access to those compressed values. But not to your password.**
+
+### Type mark
+OffPass will first look if the scanned QR-Code is actually an OffPass QR-Code. This is done by checking the first three charcters:
+
+```
+op:jA0ECQMC+t514sews8e70jsBw4SWsYYgPGzi5Ps0OGr8/tVGngopmHDQpSpMkNtkWZU573zNsFyk VVN3elnAY0D+EIIzTpKxq0F3fQ==
+```
+
+This `op:` tells the program that this is actully a OffPass QR-Code. If this is not present, OffPass will abort further steps and notify the user that this is not an OffPass QR-Code.
