示例1: VerifySignatures
// VerifySignatures checks the we have sufficient valid signatures for the given role
func VerifySignatures(s *data.Signed, role string, db *keys.KeyDB) error {
if len(s.Signatures) == 0 {
return ErrNoSignatures
}
roleData := db.GetRole(role)
if roleData == nil {
return ErrUnknownRole
}
if roleData.Threshold < 1 {
return ErrRoleThreshold{}
}
logrus.Debugf("%s role has key IDs: %s", role, strings.Join(roleData.KeyIDs, ","))
var decoded map[string]interface{}
if err := json.Unmarshal(s.Signed, &decoded); err != nil {
return err
}
msg, err := json.MarshalCanonical(decoded)
if err != nil {
return err
}
valid := make(map[string]struct{})
for _, sig := range s.Signatures {
logrus.Debug("verifying signature for key ID: ", sig.KeyID)
if !roleData.ValidKey(sig.KeyID) {
logrus.Debugf("continuing b/c keyid was invalid: %s for roledata %s\n", sig.KeyID, roleData)
continue
}
key := db.GetKey(sig.KeyID)
if key == nil {
logrus.Debugf("continuing b/c keyid lookup was nil: %s\n", sig.KeyID)

}
// method lookup is consistent due to Unmarshal JSON doing lower case for us.
method := sig.Method
verifier, ok := Verifiers[method]
if !ok {
logrus.Debugf("continuing b/c signing method is not supported: %s\n", sig.Method)
continue
}
if err := verifier.Verify(key, sig.Signature, msg); err != nil {

continue
}
valid[sig.KeyID] = struct{}{}
}
if len(valid) < roleData.Threshold {
return ErrRoleThreshold{}
}
return nil
}示例2: copyTimestampKey
func copyTimestampKey(t *testing.T, fromKeyDB *keys.KeyDB,
toStore storage.MetaStore, gun string) {
role := fromKeyDB.GetRole(data.CanonicalTimestampRole)
assert.NotNil(t, role, "No timestamp role in the KeyDB")
assert.Len(t, role.KeyIDs, 1, fmt.Sprintf(
"Expected 1 timestamp key in timestamp role, got %d", len(role.KeyIDs)))
pubTimestampKey := fromKeyDB.GetKey(role.KeyIDs[0])

"Timestamp key specified by KeyDB role not in KeysDB")
err := toStore.SetKey(gun, data.CanonicalTimestampRole, pubTimestampKey.Algorithm(),
