Scrypt Hashing/Verification Tool

Generate Hash

Plaintext Password

Salt It is recommended to use a randomly generated salt

N (CPU/Memory Cost Parameter) Must be a power of 2, determines memory and computation cost

r (Block Size Parameter) Affects memory access patterns

p (parallelization parameter) Degree of parallelism, usually set to 1

dkLen (key length) Length of the generated hash key

Hash result

Verify password

p (parallelization parameter)

dkLen (key length)

Hash value

About Scrypt:

Scrypt is a password hashing function specifically designed to resist large-scale brute force attacks using custom hardware. Compared to bcrypt, scrypt requires a large amount of memory resources, which greatly increases the cost of attacks using ASIC, FPGA, and similar hardware.

Parameter description:
• password: The password to be hashed
• salt: Salt value to enhance security
• N: CPU/memory cost parameter (must be a power of 2)
• r: Block size parameter
• p: Parallelization parameter
• dkLen: Derived key length (bytes)

Recommended settings: N=16384, r=8, p=1, dkLen=32. The hash is one-way and cannot be reversed to retrieve the original password.
