For example, using a certificate downloaded from, when the following command is given:

$$ ssh-certview -width 70 ca-certificate.cer

The following output is produced:

Certificate =
  SubjectName = <C=FI, O=SSH Communications Security Corp, CN=Secure
    Shell Test CA>
  IssuerName = <C=FI, O=SSH Communications Security Corp, CN=Secure

  SignatureAlgorithm = rsa-pkcs1-sha1
  Certificate seems to be self-signed.
