Overview ¶
Package nonce_cache provides a mechanism for managing nonce storage and checking for replay attacks. It implements a NonceCache type that stores nonces with timestamps and allows for expiration of old nonces to prevent memory exhaustion.

Types ¶
type NonceCache ¶
type NonceCache struct {
// contains filtered or unexported fields
}
NonceCache manages nonce storage and checks for replay attacks.
func NewNonceCache ¶
func NewNonceCache(expiryTime time.Duration) *NonceCache
NewNonceCache creates a new NonceCache with the specified expiry time for nonces.
func (*NonceCache) CleanupExpiredNonces ¶
func (nc *NonceCache) CleanupExpiredNonces()
CleanupExpiredNonces removes nonces that have expired from the cache.
func (*NonceCache) Exists ¶
func (nc *NonceCache) Exists(nonce []byte) bool
Exists checks if a nonce exists in the cache or not
func (*NonceCache) Load ¶
func (nc *NonceCache) Load(nonce []byte) (any, bool)
Load loads a nonce from the cache.
func (*NonceCache) StartCleanupRoutine ¶
func (nc *NonceCache) StartCleanupRoutine(ctx context.Context, cleanupInterval time.Duration)
StartCleanupRoutine starts a background routine to periodically clean up expired nonces. It runs the cleanup every cleanupInterval, and listens for cancellation via context.
func (*NonceCache) Store ¶
func (nc *NonceCache) Store(nonce []byte) error
Store stores a nonce in the cache. If the nonce already exists, it returns an error.
