Password format in OC_USERS db?

I have password on OC_USERS like:

3|$argon2id$v=19$m=65536,t=4,p=1$YjJOclZ4bG1Q...blah blah..XsdtIqE

I tried to find a C library on Argon2id to no avail. Does anyone know?

First off, you’re in the wrong category. This category is about the passwords app, not how NC handles passwords.

Second, you’re probably doing something wrong when you are trying to work with the data stored by Nc in the database. Use the ./occ command in the root directory of your installation to manage users passwords.

And lastly, the Argon2 algorithm is part of libsodium. Here is the documentation: .
