Example 1 with ASN1String

use of org.webpki.asn1.ASN1String in project bitcoinj by bitcoinj.

the class X509Utils method getDisplayNameFromCertificate.

 * in a web browser, or null if one cannot be extracted. This will typically be the common name (CN) field, but
 * can also be the org (O) field, org+location+country if withLocation is set, or the email
 * address for S/MIME certificates.
