Class CASN1EncBitString

class CASN1EncBitString : public CASN1EncPrimitive;

Description

Class for encoding bit strings (keys, for example).

Derivation

• CBase - Base class for all classes to be instantiated on the heap

• CASN1EncBase - Base class for all ASN.1 types that we can encode

• CASN1EncPrimitive - All ASN1 primitive type encoding classes derive from here

• CASN1EncBitString - Class for encoding bit strings (keys, for example)

static IMPORT_C CASN1EncBitString *NewLC(const TDesC8 &aBitStr);

Description

Constructs a new DER bit string encoder from a bit string that does not have unused bits at the end, i.e. is octet-aligned. The passed string must be in big-endian format.

Parameters

const TDesC8 &aBitStr Octet-aligned bit string.

Return value

CASN1EncBitString * A new DER bit string encoder object, which is left on the cleanup stack.

static IMPORT_C CASN1EncBitString *NewL(const TDesC8 &aBitStr);

Description

Constructs a new DER bit string encoder from a bit string that does not have unused bits at the end, i.e. is octet-aligned. The passed string must be in big-endian format.

Parameters

const TDesC8 &aBitStr Octet-aligned bit string.

Return value

CASN1EncBitString * A new DER bit string encoder object.

static IMPORT_C CASN1EncBitString *NewLC(const TDesC8 &aBitStr, TUint aLengthBits);

Description

Constructs a new DER bit string encoder from a bit string that is not octet-aligned, which means it has unused bits in its last octet. The passed string must be in big-endian format.

Parameters

const TDesC8 &aBitStr Bit string. TUint aLengthBits Length in bits of the passed bit string. The function will panic if is greater than the actual bit length of , or the difference is more that 7 bits.

Return value

CASN1EncBitString * A new DER bit string encoder object which is left on the cleanup stack.

static IMPORT_C CASN1EncBitString *NewL(const TDesC8 &aBitStr, TUint aLengthBits);

Description

Constructs a new DER bit string encoder from a bit string that is not octet-aligned, which means it has unused bits in its last octet. The passed string must be in big-endian format.

Parameters

const TDesC8 &aBitStr Bit string. TUint aLengthBits Length in bits of the passed bit string. The function will panic if is greater than the actual bit length of , or the difference is more that 7 bits.

Return value

CASN1EncBitString * A new DER bit string encoder object.

static IMPORT_C CASN1EncBitString *NewL(const CASN1EncBase &aAsnObj);

Description

Wraps the passed encoding object into a bit string.

Parameters

const CASN1EncBase &aAsnObj Encoding object to wrap.

Return value

CASN1EncBitString * A new bit string containing the passed encoding object.

static IMPORT_C CASN1EncBitString *NewLC(const CASN1EncBase &aAsnObj);

Description

Wraps the passed encoding object into a bit string.

Parameters

const CASN1EncBase &aAsnObj Encoding object to wrap.

Return value

CASN1EncBitString * A new bit string containing the passed encoding object on the cleanup stack.
