CCMSKeyIdentifier Class Reference

class CCMSKeyIdentifier : public CCMSSequence

This module handles two ASN.1 types, RecipientKeyIdentifier and KEKIdentifier.

ASN.1 definitions: RecipientKeyIdentifier ::= SEQUENCE { subjectKeyIdentifier SubjectKeyIdentifier, date GeneralizedTime OPTIONAL, other OtherKeyAttribute OPTIONAL }

SubjectKeyIdentifier ::= OCTET STRING

KEKIdentifier ::= SEQUENCE { keyIdentifier OCTET STRING, date GeneralizedTime OPTIONAL, other OtherKeyAttribute OPTIONAL }

NewL()

IMPORT_C CCMSKeyIdentifier *

NewL

(

)

[static]

Two-phased constructor.

NewL(const TDesC8 &)

IMPORT_C CCMSKeyIdentifier *

NewL

(

const TDesC8 &

aKeyIdentifier

)

[static]

Two-phased constructor. Copies of the parameters are made.

Parameters

const TDesC8 & aKeyIdentifier

identifies the recipient's certificate or the the key-encryption key that was previously distributed to the sender and one or more recipients.

NewL(const TDesC8 &, const TTime &)

IMPORT_C CCMSKeyIdentifier *	NewL	(	const TDesC8 &	aKeyIdentifier,
			const TTime &	aDate
		)	[static]

Two-phased constructor. Copies of the parameters are made.

Parameters

const TDesC8 & aKeyIdentifier	identifies the recipient's certificate or the the key-encryption key that was previously distributed to the sender and one or more recipients.
const TTime & aDate	specifies which of the recipient's previously distributed UKMs was used by the sender. In case of KEKIdentifier, specifies a single key-encryption key from a set.
