Class KeyGrip

java.lang.Object

org.eclipse.jgit.gpg.bc.internal.keys.KeyGrip

public final class KeyGrip
extends Object

Utilities to compute the keygrip of a key. A keygrip is a SHA1 hash over the public key parameters and is used internally by the gpg-agent to find the secret key belonging to a public key: the secret key is stored in a file under ~/.gnupg/private-keys-v1.d/ with a name "<keygrip>.key". While this storage organization is an implementation detail of GPG, the way keygrips are computed is not; they are computed by libgcrypt and their definition is stable.
