Crypt::OpenPGP::Buffer - Binary in/out buffer


    use Crypt::OpenPGP::Buffer;
    my $buf = Crypt::OpenPGP::Buffer->new;
    my $m = $buf->get_mp_int;


Crypt::OpenPGP::Buffer subclasses the Data::Buffer class to provide binary in/out buffer capabilities for Crypt::OpenPGP. In addition to the standard Data::Buffer methods, this class adds methods to get and put multiple-precision integers (Math::Pari objects).

A PGP multiple precision integer is stored in two pieces: a two-octet scalar representing the length of the integer in bits, followed by a string of octets that is a serialized representation of the integer.


As Crypt::OpenPGP::Buffer subclasses Data::Buffer there is no need to reproduce the entire documentation of the latter module. Thus this usage section will include only the methods added by Crypt::OpenPGP::Buffer.


Grabs a multiple-precision integer from the buffer $buf (starting after the current offset position in the buffer) and returns that integer.


Serializes a multiple-precision integer into the buffer in the above form (two-octet bitsize, string of octets).
