Constructor & Destructor Documentation

Asn1DerEncodeBuffer

(

)

This constructor creates a DER encode buffer object with the default size increment. Whenever the buffer becomes full, the buffer will be expanded by the sizeIncrement size.

Asn1DerEncodeBuffer

(

int

sizeIncrement

)

This constructor creates a DER encode buffer object with the given size increment. Whenever the buffer becomes full, the buffer will be expanded by the sizeIncrement size. This size should be large enough to prevent resizing in normal operation.

Parameters:

sizeIncrement

The initial size in bytes of an encode buffer. If the buffer becomes full, it will be expanded by this amount.

override int TrimBitString

(

Asn1BitString

bitstr

)

[virtual]

This method will trim a BIT STRING for DER encoding by removing all zero trailing bits.

<param name="bitstr> ASN.1 BIT STRING object <return> Adjusted bit count </return>
