No verification is done of the certificate - signature; the caller should check the fingerprint, - <i>sha1(cert)</i>, against a table or check the certificate by other - means. X.509 certificates are often stored in PEM format; use - <i>dec64</i> to convert to binary before computing the fingerprint or - calling <i>X509toRSApub</i>.
