Class OtpChallenge

java.lang.Object
org.bouncycastle.asn1.ASN1Object
org.bouncycastle.asn1.est.OtpChallenge
All Implemented Interfaces:
org.bouncycastle.asn1.ASN1Encodable, org.bouncycastle.util.Encodable
public class OtpChallenge extends org.bouncycastle.asn1.ASN1Object
RFC 7894 ยง3.1 otpChallenge attribute: a one-time password value conveyed as part of a CSR request. The companion OTP generation and verification mechanisms (e.g. RFC 4226 HOTP, RFC 6238 TOTP) are out of scope. 
otpChallenge ATTRIBUTE ::= {
    WITH SYNTAX DirectoryString {ub-aa-otpChallenge}
    EQUALITY MATCHING RULE caseExactMatch
    SINGLE VALUE TRUE
    ID id-aa-otpChallenge
}
ub-aa-otpChallenge INTEGER ::= 255
Identified by PKCSObjectIdentifiers.id_aa_otpChallenge.

    • fromAttribute

      public static OtpChallenge fromAttribute(org.bouncycastle.asn1.pkcs.Attribute attribute)
      Extract the otpChallenge value carried by a PKCS#9 Attribute.
      Throws:
      IllegalArgumentException - if the attribute is not PKCSObjectIdentifiers.id_aa_otpChallenge or does not carry exactly one value.

    • getAttrType

      protected org.bouncycastle.asn1.ASN1ObjectIdentifier getAttrType()
      The attribute-type OID for this RFC 7894 attribute. Used by toAttribute() to wrap the value in a PKCS#9 Attribute.

    • getValue

      public org.bouncycastle.asn1.x500.DirectoryString getValue()
      Return the value as a DirectoryString.

    • getString

      public String getString()
      Return the value as a Java String, decoded from whichever underlying DirectoryString encoding was used.

    • toAttribute

      public org.bouncycastle.asn1.pkcs.Attribute toAttribute()
      Wrap this value in a PKCS#9 Attribute carrying the RFC 7894 OID, ready for inclusion in a CertificationRequest's attributes set (or in a CSR-Attributes response).
      Returns:
      an Attribute of the form (oid, {value}).
