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 §3.1 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.

Method Detail

getInstance

public static OtpChallenge getInstance(java.lang.Object obj)

fromAttribute

public static OtpChallenge fromAttribute(org.bouncycastle.asn1.pkcs.Attribute attribute)

Extract the otpChallenge value carried by a PKCS#9 Attribute.

Throws:

java.lang.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 java.lang.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}).
