deps: Bump libsodium from 1.0.20.1 to 1.0.22

[dependabot]

Updated libsodium from 1.0.20.1 to 1.0.22.

Release notes

Sourced from libsodium's releases.

1.0.22

Version 1.0.22

This point release includes all the changes from 1.0.21-stable, plus:

• Post-quantum key encapsulation is now available. ML-KEM768, the
  NIST-standardized lattice-based KEM, is accessible through the
  crypto_kem_mlkem768_*() functions.
• X-Wing, a hybrid KEM combining ML-KEM768 with X25519 for protection
  against both classical and quantum adversaries, is available through the
  crypto_kem_*() functions. X-Wing is the recommended KEM for most
  applications.
• SHA-3 hash functions are now available as crypto_hash_sha3256_*()
  and crypto_hash_sha3512_*(), with both one-shot and streaming APIs.

Version 1.0.21-stable

• Performance: NEON optimizations for Argon2 on ARM platforms.
• Performance: SHA3 (Keccak1600) now leverages ARM SHA3 instructions when
  available on ARM platforms.
• Performance: WebAssembly SIMD implementations of Argon2 have been added.
• Emscripten: LTO is now disabled. With Emscripten 4, LTO produced
  WebAssembly modules with functions that ran significantly slower than
  without it.
• Emscripten: a new option allows compilation with SIMD support.
• Emscripten: native ESM module generation is now supported.
• JavaScript sumo builds now allow up to 80 MiB memory usage, so that
  crypto_pwhash with the interactive settings can be used in pure
  JavaScript, not just WebAssembly.
• XOF state alignment has been relaxed.
• crypto_core_keccak1600_state has been added.
• Export missing crypto_ipcrypt_nd_keygen() helper function.
• crypto_auth_hmacsha256_init and crypto_auth_hmacsha512_init now
  accept NULL key pointers (with a zero key length), for consistency with
  other _init functions.
• apple-xcframework: headers are now in a Clibsodium subdirectory
  to prevent module.modulemap collisions with other xcframeworks.
• Fixed compilation with GCC on aarch64 and gcc 4.x.
• On aarch64, aes256-gcm is now enabled even when not using clang,
  including MSVC.
• Added compatibility with Visual Studio 2026 when toolsets do not
  define PlatformToolsetVersion.
• Libsodium can be directly used as a dependency in a Zig project.
• Performance of MSVC builds has been improved.

1.0.21

• Version 1.0.21
  This point release includes all the changes from 1.0.20-stable, which include a security fix for the crypto_core_ed25519_is_valid_point() function, as well as two new sets of functions:

  • The new crypto_ipcrypt_* functions implement mechanisms for securely encrypting and anonymizing IP addresses.
  • The sodium_bin2ip and sodium_ip2bin helper functions have been added to complement the crypto_ipcrypt_* functions and easily convert addresses between bytes and strings.
  • XOF: the crypto_xof_shake* and crypto_xof_turboshake* functions are standard extendable output functions. From input of any length, they can derive output of any length with the same properties as hash functions. These primitives are required by many post-quantum mechanisms, but can also be used for a wide range of applications, including key derivation, session encryption and more.

• Version 1.0.20-stable

  • XCFramework: cross-compilation is now forced on Apple Silicon to avoid Rosetta-related build issues
  • The Fil-C compiler is supported out of the box
  • The CompCert compiler is supported out of the box
  • MSVC 2026 (Visual Studio 2026) is now supported
  • Zig builds now support FreeBSD targets
  • Performance of AES256-GCM and AEGIS on ARM has been improved with some compilers
  • Android binaries have been added to the NuGet package
  • Windows ARM binaries have been added to the NuGet package
  • The Android build script has been improved. The base SDK is now 27c, and the default platform is 21, supporting 16 KB page sizes.
  • The library can now be compiled with Zig 0.15 and Zig 0.16
  • Zig builds now generate position-independent static libraries by default on targets that support PIC
  • arm64e builds have been added to the XCFramework packages
  • XCFramework packages are now full builds instead of minimal builds
  • MSVC builds have been enabled for ARM64
  • iOS 32-bit (armv7/armv7s) support has been removed from the XCFramework build script
  • Security: optblockers have been introduced in critical code paths to prevent compilers from introducing unwanted side channels via conditional jumps. This was observed on RISC-V targets with specific compilers and options.
  • Security: crypto_core_ed25519_is_valid_point() now properly rejects small-order points that are not in the main subgroup
  • ((nonnull)) attributes have been relaxed on some crypto_stream* functions to allow NULL output buffers when the output length is zero
  • A cross-compilation issue with old clang versions has been fixed
  • JavaScript: support for Cloudflare Workers has been added
  • JavaScript: WASM_BIGINT is forcibly disabled to retain compatibility with older runtimes
  • A compilation issue with old toolchains on Solaris has been fixed
  • crypto_aead_aes256gcm_is_available is exported to JavaScript
  • libsodium is now compatible with Emscripten 4.x
  • Security: memory fences have been added after MAC verification in AEAD to prevent speculative access to plaintext before authentication is complete
  • Assembly files now include .gnu.property notes for proper IBT and Shadow Stack support when building with CET instrumentation.
