class: Checksum

[24:7] extends: object

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 GChecksum, use [ctor@GLib.Checksum.new]. To free a GChecksum, use [method@GLib.Checksum.free]. GLib supports incremental checksums using the GChecksum data structure, by calling [method@GLib.Checksum.update] as long as there’s data available and then using [method@GLib.Checksum.get_string] or [method@GLib.Checksum.get_digest] 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.

Methods

• Checksum (Handle = null)

  Creates a new Checksum by wrapping a native handle or another wrapper.

  • @p Handle is the native handle or another wrapper whose handle to adopt.

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.
