options

1️⃣ memoryCost?: number | undefined | null

The amount of memory to be used by the hash function, in kilobytes. Each thread will have a memory pool of this size. Note that large values for highly concurrent usage will cause starvation and thrashing if your system memory gets full.

• Value is an integer in decimal (1 to 10 digits), between 1 and (2^32)-1.
• The default value is 4096, meaning a pool of 4 MiB per thread.

2️⃣ memoryCost?: number | undefined | null

The time cost is the amount of passes (iterations) used by the hash function. It increases hash strength at the cost of time required to compute.

• Value is an integer in decimal (1 to 10 digits), between 1 and (2^32)-1.
• The default value is 3.

3️⃣ timeCost?: number | undefined | null

The hash length is the length of the hash function output in bytes. Note that the resulting hash is encoded with Base 64, so the digest will be ~1/3 longer.

• The default value is 32, which produces raw hashes of 32 bytes or digests of 43 characters.

4️⃣ outputLen?: number | undefined | null

The amount of threads to compute the hash on. Each thread has a memory pool with memoryCost size. Note that changing it also changes the resulting hash.

• Value is an integer in decimal (1 to 3 digits), between 1 and 255.
• The default value is 1, meaning a single thread is used.

5️⃣ parallelism?: number | undefined | null

6️⃣ algorithm?: Algorithm | undefined | null

7️⃣ version?: Version | undefined | null

8️⃣ secret?: Buffer | undefined | null
