Signature

secure_compare(a, b)

Secure string comparison for strings of variable length.

While a timing attack would not be able to discern the content of a secret compared via secure_compare, it is possible to determine the secret length. This should be considered when using secure_compare to compare weak, short secrets to user input.

Parameters

a req
b req
