|
* Scrypt KDF from RFC 7914. |
|
* @param password - pass |
|
* @param salt - salt |
|
* @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 |
|
* @example |
|
* scrypt('password', 'salt', { N: 2**18, r: 8, p: 1, dkLen: 32 }); |
