MarsSeed [1] filed a request to merge cryptsetup-nested-cryptkey [2] into cryptsetup-sigfile [3]: 'cryptsetup-nested-cryptkey' is an unmaintained older variant of cryptsetup v2.4.3. 'cryptsetup-sigfile' seems to be the successor based on the latest cryptsetup (v2.6.1). The latter also has provides=cryptsetup-nested-cryptkey.
