argon2 is an R package for secure password hashing via the argon2 algorithm. It is a relatively new hashing algorithm and is believed to be very secure. The package also includes some utilities that should be useful for digest authentication, including a wrapper of blake2b. For similar R packages, see sodium and bcrypt.
The package includes a source distribution of the latest implementation from the argon2 developers: https://github.com/P-H-C/phc-winner-argon2. Note that we are unaffiliated with their project; if we break something, don’t blame them!
You can install the stable version from CRAN using the usual
