## Class DisplayText

- java.lang.Object
- - org.bouncycastle.asn1.ASN1Object
  - - org.bouncycastle.asn1.x509.DisplayText

- All Implemented Interfaces:
    ASN1Choice, ASN1Encodable, Encodable

      public class DisplayText
      extends ASN1Object
      implements ASN1Choice

  `DisplayText` class, used in `CertificatePolicies` X509 V3 extensions (in policy qualifiers).

  It stores a string in a chosen encoding.

       DisplayText ::= CHOICE {
            ia5String        IA5String      (SIZE (1..200)),
            visibleString    VisibleString  (SIZE (1..200)),
            bmpString        BMPString      (SIZE (1..200)),
            utf8String       UTF8String     (SIZE (1..200)) }
