CalculateContentsLengthDER()
| void | CalculateContentsLengthDER | ( | ) | [private, virtual] |
Calculates length of DER-encoded bit string contents. For non empty bit strings this differs from octet string in the extra leading byte containing the number of unused bits in the last octet.
ConstructL(const TDesC8 &)
| void | ConstructL | ( | const TDesC8 & | aBitStr | ) | [private] |
ConstructL(const TDesC8 &, TUint)
| void | ConstructL | ( | const TDesC8 & | aBitStr, |
| | TUint | aLengthBits |
| | ) | [private] |
ConstructL(const CASN1EncBase &)
Constructs bit string from ASN.1 encoding object.
Note: First produces raw DER encoding from the object, then creates a bit string using other construct function.
Parameters
| const CASN1EncBase & aAsnObj | ASN.1 encoding object to wrap in bit string. |
NewL(const TDesC8 &)
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. |
NewL(const TDesC8 &, TUint)
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 aLengthBits is greater than the actual bit length of aBitString, or the difference is more that 7 bits. |
NewL(const CASN1EncBase &)
Wraps the passed encoding object into a bit string.
NewLC(const TDesC8 &)
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. |
NewLC(const TDesC8 &, TUint)
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 aLengthBits is greater than the actual bit length of aBitString, or the difference is more that 7 bits. |
NewLC(const CASN1EncBase &)
Wraps the passed encoding object into a bit string.
WriteContentsDERL(TDes8 &)
| void | WriteContentsDERL | ( | TDes8 & | aBuf | ) | const [private, virtual] |
Writes DER-encoded bit string contents to aBuf. Prepends the actual bit string octets with extra octet containing number of unused bits in the last octet. Before writing, converts contents of the bit string to big-endian form.
Parameters
| TDes8 & aBuf | Buffer to write to; must be long enough; see CalculateContentsLengthDER method. |
