N
– iterations count (affects memory and CPU usage), e.g. 16384 or 2048r
– block size (affects memory and CPU usage), e.g. 8p
– parallelism factor (threads to run in parallel - affects the memory, CPU usage), usually 1password
– the input password (8-10 chars minimal length is recommended)salt
– securely-generated random bytes (64 bits minimum, 128 bits recommended)derived-key-length
- how many bytes to generate as output, e.g. 32 bytes (256 bits)scrypt
using the command:scrypt
package depends on OpenSSL, so first install it in its default location (e.g. in C:\OpenSSL-Win64
in Windows), then install the scrypt Python package.scrypt
package is successfully installed, write the Python code to calculate a Scrypt hash:
(Note, we have chosen smaller number for iterations count. We did that just to increase the following example execution speed. In common usage, a higher iterations count is recommended, e.g. 16384 - see above.)$
character. For example, the password [email protected]~123
can be stored in the Scrypt standard format like this (several examples are given, to make the pattern apparent):
