Struct KeyGrip 

pub struct KeyGrip { /* private fields */ }

KeyGrip struct manages a set of cryptographic keys Provides both thread-safe (RwLock) and non-thread-safe implementations

Implementations

impl KeyGrip

pub fn new(keys: Vec<Vec<u8>>) -> Result<Self, Error>

Creates a new KeyGrip instance with non-thread-safe key storage Returns error if keys vector is empty

pub fn new_with_lock(keys: Vec<Vec<u8>>) -> Result<Self, Error>

Creates a new KeyGrip instance with thread-safe key storage using RwLock

pub fn update_keys(&self, new_keys: Vec<Vec<u8>>)

Updates the keys in the thread-safe storage No-op if using non-thread-safe storage

pub fn sign(&self, data: &[u8]) -> Result<String, Error>

Signs the input data using the first key in the key set Returns error if no keys are available

pub fn verify(&self, data: &[u8], digest: &str) -> Result<(bool, bool), Error>

Verifies a signature (digest) against the input data Returns tuple (is_valid, is_current):

• is_valid: true if signature matches any key
• is_current: true if signature matches the current (first) key
