public class OtpChallenge

extends org.bouncycastle.asn1.est.CSRChallengeAttribute

RFC 7894 §3.1 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 Summary

static OtpChallenge	fromAttribute(Attribute attribute) Extract the value carried by a PKCS#9 Attribute.
protected ASN1ObjectIdentifier	getAttrType() The attribute-type OID for this RFC 7894 attribute.
static OtpChallenge	getInstance(java.lang.Object obj)
java.lang.String	getString() Return the value as a Java String, decoded from whichever underlying encoding was used.
DirectoryString	getValue() Return the value as a DirectoryString.
ASN1Primitive	toASN1Primitive() Method providing a primitive representation of this object suitable for encoding.
Attribute	toAttribute() Wrap this value in a PKCS#9 Attribute carrying the RFC 7894 OID, ready for inclusion in a 's set (or in a CSR-Attributes response).

Method Detail

getInstance

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

fromAttribute

public static OtpChallenge fromAttribute(Attribute attribute)

Extract the 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 ASN1ObjectIdentifier getAttrType()

Description copied from class: org.bouncycastle.asn1.est.CSRChallengeAttribute

The attribute-type OID for this RFC 7894 attribute. Used by CSRChallengeAttribute.toAttribute() to wrap the value in a PKCS#9 Attribute.

getValue

public 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 encoding was used.

toAttribute

public Attribute toAttribute()

Wrap this value in a PKCS#9 Attribute carrying the RFC 7894 OID, ready for inclusion in a 's set (or in a CSR-Attributes response).

Returns:

an of the form )}.

toASN1Primitive

public ASN1Primitive toASN1Primitive()

Description copied from class: ASN1Object

Method providing a primitive representation of this object suitable for encoding.

Specified by:

toASN1Primitive in interface ASN1Encodable

Specified by:

toASN1Primitive in class ASN1Object

Returns:

a primitive representation of this object.
