* @param opts - parameters
|
|
* - `N` is cpu/mem work factor (power of 2 e.g. 2**18)
|
|
* - `r` is block size (8 is common), fine-tunes sequential memory read size and performance
|
|
* - `p` is parallelization factor (1 is common)
|
|
* - `dkLen` is output key length in bytes e.g. 32.
|
|
* - `asyncTick` - (default: 10) max time in ms for which async function can block execution
|
|
* - `maxmem` - (default: `1024 ** 3 + 1024` aka 1GB+1KB). A limit that the app could use for scrypt
|
|
* - `onProgress` - callback function that would be executed for progress report
|
|
* @returns Derived key
