DecodeDERL(const TDesC8 &)

IMPORT_C CDecPKCS8Data *

DecodeDERL

(

const TDesC8 &

aBinaryData

)

[static]

Decodes DER encoded ASN1 data representing a PKCS#8 clear text private key. See the PKCS#8 specifications for the ASN1 syntax.

Parameters

const TDesC8 & aBinaryData

A descriptor containing the ASN1 data.

DecodeEncryptedDERL(const TDesC8 &, const TDesC8 &)

IMPORT_C CDecPKCS8Data *	DecodeEncryptedDERL	(	const TDesC8 &	aBinaryData,
			const TDesC8 &	aPassword
		)	[static]

Decodes DER encoded ASN1 data representing a PKCS#8 encrypted private key. See the PKCS#8 specifications for the ASN1 syntax.

Parameters

const TDesC8 & aBinaryData	A descriptor containing the ASN1 data.
const TDesC8 & aPassword	The password to decrypt the key.

IsASN1Sequence(const TDesC8 &, TInt &)

TBool	IsASN1Sequence	(	const TDesC8 &	aBinaryData,
			TInt &	aPos
		)	[private, static]

Determine if the some data represents the start of an ASN1 sequence. The data is specified by a descriptor and an offset. If the data matches, the offset is advanced to point to the contents of the sequence.

Parameters

const TDesC8 & aBinaryData
TInt & aPos

IsEncryptedPKCS8Data(const TDesC8 &)

IMPORT_C TBool

IsEncryptedPKCS8Data

(

const TDesC8 &

aBinaryData

)

[static]

Determines if some binary data is an encrypted pkcs#8 private key.

Parameters

const TDesC8 & aBinaryData

A descriptor containing the data.

IsExpectedData(const TDesC8 &, TInt &, const TDesC8 &)

TBool	IsExpectedData	(	const TDesC8 &	aBinaryData,
			TInt &	aPos,
			const TDesC8 &	aExpectedData
		)	[private, static]

Determine if some data starts with an expected string. The data is specified by a descriptor and an offset. If the data matches, the offset is advanced to point after the match.

Parameters

const TDesC8 & aBinaryData
TInt & aPos
const TDesC8 & aExpectedData

IsPKCS8Data(const TDesC8 &)

IMPORT_C TBool

IsPKCS8Data

(

const TDesC8 &

aBinaryData

)

[static]

Determines if some binary data is a pkcs#8 clear text private key.

Parameters

const TDesC8 & aBinaryData

A descriptor containing the data. This must be at least KIsPKCS8DataMinLength bytes long.
