Module ct 

Constant-time comparison utilities.

These functions are resistant to timing attacks and should be used when comparing cryptographic values like MACs, signatures, or hashes.

Structs

SecretBytes

A wrapper for sensitive data that implements constant-time comparison.

Functions

ct_eq

Compare two byte slices in constant time.

ct_eq_32

Compare two 32-byte arrays in constant time.

ct_eq_64

Compare two 64-byte arrays in constant time (for signatures).

ct_eq_slice_32

Compare a slice against a fixed-size array in constant time.

ct_select

Select between two values in constant time based on a condition.
