Enum zbox::OpsLimit

pub enum OpsLimit {
    Interactive,
    Moderate,
    Sensitive,
}

Password hash operation limit.

It represents a maximum amount of computations to perform. Higher level will require more CPU cycles to compute. It is often used with MemLimit.

For interactive, online operations, OpsLimit::Interactive and MemLimit::Interactive provide base line for these two parameters. This requires 64 MB of dedicated RAM. Higher values may improve security.

Alternatively, OpsLimit::Moderate and MemLimit::Moderate can be used. This requires 256 MB of dedicated RAM, and takes about 0.7 seconds on a 2.8 Ghz Core i7 CPU.

For highly sensitive data and non-interactive operations, OpsLimit::Sensitive and MemLimit::Sensitive can be used. With these parameters, deriving a key takes about 3.5 seconds on a 2.8 Ghz Core i7 CPU and requires 1024 MB of dedicated RAM.
