SECURITY UPDATE (CVE-2026-30910): Combined aead encryption, combined signature
creation, and bin2hex functions did not check that output size will be less
than SIZE_MAX, which could lead to integer wraparound causing an undersized
output buffer. This can cause a crash in bin2hex and encryption algorithms
other than aes256gcm. For aes256gcm encryption and signatures, an undersized
buffer could lead to buffer overflow.

Encountering this issue is unlikely as the message length would need to be very
large.

Additional changes:

- update README

0.001000 Jan 21 2026

- large re-factor (mostly just deduplication) of perl module code. one
  user-facing change: packages in the Crypt::Sodium::XS::OO:: namespace can no
  longer be imported directly. they really shouldn't have been previously, but
  it will no longer work. if any code was doing so, remove the "::OO" from the
  package name where it is imported (e.g., "use Crypt::Sodium::XS::OO::box"
  becomes "use Crypt::Sodium::XS::box") and no further changes are necessary.

- bump libsodium to version 1.0.21-stable as of Jan 21

- implement new ipcrypt feature from 1.0.21

- add related sodium_bin2ip and sodium_ip2bin from 1.0.21

- minor bugfixes and improvements

IMPORTANT SECURITY UPDATE: bundled libsodium updated to 1.0.20-stable. fixes
CVE-2025-15444 (upstream CVE-2025-69277). libsodium version 1.0.20-stable is
both a vulnerable and not-vulnerable version for this CVE. the included copy of
this "stable release" (daily snapshot) is the version of 1.0.20-stable released
January 3, 2026 which includes a fix for the vulnerability.

vulnerability notes:

- C::S::XS::curve25519::core_ed25519_is_valid_point could have improperly
  reported invalid curve points as valid. only users of this low-level function
  (e.g., for implementing custom crypto) are affected.

- this update only affects users of the bundled version of libsodium. users
  of an externally-provided libsodium (e.g., software packaged by operating
  system distribution) must update that library to a not-vulnerable version.
  for those external library users, this Crypt::Sodium::XS update is not
  necessary and will not remediate the vulnerability.

  subclassing

- minor code cleanup (sodium_bin2base64) and assorted doc updates

0.000039 Aug 21 2025

0.000036 Aug 3 2025

- important update: return protected memory from pwhash function. the output is
  intended to be used as a secret, and this was an oversight in the original
  implementation.

- add new importable shortcut functions to memvault constructors

- replace undocumented memvault new_from_ttyno constructor with new_from_tty.
  this remains undocumented and not recommended for use pending further review.

- BUGFIX: fix overread on new length parameter for memvault new_from_fd|file

- a couple documentation changes are included

0.000034 Aug 1 2025

- protected memory functions were renamed to be more sensible.
  backwards-compatability aliases are there so code won't break. new protected
  memory flag functions added. see Crypt::Sodium::XS::ProtMem.

- minor change to arguments in MemVault new_from_fd|new_from_file. now takes an
  optional size argument before flags. pretty unlikely anyone was calling these
  with flags before, but if so it needs updating.

- update csxs-ppcrypt demo program. NOTE: arguments to this program have
  changed. encryption format has been extended, but is backwards compatible.

- fixes for pminisign demo program.

- test cleanup, and always disable strict mlock in tests.

- minor bugfixes and improvements

  derivation of duplicate keys. see docs for details.
