Release 0.6.36 of the digest package arrived at CRAN today and has also been uploaded to Debian.
digest
creates hash digests of arbitrary R objects. It can use a number
different hashing algorithms (md5
, sha-1
,
sha-256
, sha-512
, crc32
,
xxhash32
, xxhash64
, murmur32
,
spookyhash
, blake3
,crc32c
,
xxh3_64
and xxh3_128
), and enables easy
comparison of (potentially large and nested) R language objects as it
relies on the native serialization in R. It is a mature and widely-used
package (with 69.1 million downloads just on the partial cloud mirrors
of CRAN which keep logs) as many tasks may involve caching of
objects for which it provides convenient general-purpose hash key
generation to quickly identify the various objects.
This release updates one contributed C++ function to be compliant
with R’s revent preference for explicit declaration of
REMAP
, and improves the behavior under the (increasingly
rare) ‘big endian’ system via a patch to blake3
as well as
a hint that spookyhash
under ‘big endian’ may not meed its
reference output from ‘little endian’.
