Checksum

GLib provides a generic API for computing checksums (or ‘digests’) for a sequence of arbitrary bytes, using various hashing algorithms like MD5, SHA-1 and SHA-256. Checksums are commonly used in various environments and specifications.

To create a new glib.checksum.Checksum, use glib.checksum.Checksum.new_. To free a glib.checksum.Checksum, use glib.checksum.Checksum.free.

GLib supports incremental checksums using the glib.checksum.Checksum data structure, by calling glib.checksum.Checksum.update as long as there’s data available and then using glib.checksum.Checksum.getString or glib.checksum.Checksum.getDigest to compute the checksum and return it either as a string in hexadecimal form, or as a raw sequence of bytes. To compute the checksum for binary blobs and nul-terminated strings in one go, use the convenience functions func@GLib.compute_checksum_for_data and func@GLib.compute_checksum_for_string, respectively.

class Checksum : Boxed {

this(glib.types.ChecksumType checksumType);

glib.checksum.Checksum copy();

string getString();

void reset();

void update(ubyte[] data);

static ptrdiff_t typeGetLength(glib.types.ChecksumType checksumType);

}

Constructors

this this(glib.types.ChecksumType checksumType): Creates a new #GChecksum, using the checksum algorithm checksum_type. If the checksum_type is not known, null is returned. A #GChecksum can be used to compute the checksum, or digest, of an arbitrary binary blob, using different hashing algorithms.

Members

Functions

copy glib.checksum.Checksum copy(): Copies a #GChecksum. If checksum has been closed, by calling glib.checksum.Checksum.getString or glib.checksum.Checksum.getDigest, the copied checksum will be closed as well.
getString string getString(): Gets the digest as a hexadecimal string.
reset void reset(): Resets the state of the checksum back to its initial state.
update void update(ubyte[] data): Feeds data into an existing #GChecksum. The checksum must still be open, that is glib.checksum.Checksum.getString or glib.checksum.Checksum.getDigest must not have been called on checksum.

Static functions

typeGetLength ptrdiff_t typeGetLength(glib.types.ChecksumType checksumType): Gets the length in bytes of digests of type checksum_type
