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
}

if roleData == nil {
return ErrUnknownRole
}
if roleData.Threshold < 1 {
return ErrRoleThreshold{}
}

var decoded map[string]interface{}
if err := json.Unmarshal(s.Signed, &decoded); err != nil {
return err
}
msg, err := json.MarshalCanonical(decoded)
if err != nil {

assert.NotNil(t, role, "No timestamp role in the KeyDB")
