• Switched to OpenSSL 3.6, with full compatibility with the latest OpenSSL 3.6.0 (1.10.2025) version, which provides new features and improvements, including:
• Added NIST security categories for PKEY objects.
• Added support for EVP_SKEY opaque symmetric key objects to the key derivation and key exchange provider methods.
• Added EVP_KDF_CTX_set_SKEY(), EVP_KDF_derive_SKEY(), and EVP_PKEY_derive_SKEY() functions.
• Added LMS signature verification support as per [SP 800-208].
• Added an openssl configutl utility for processing the OpenSSL configuration file and dumping the equal configuration file.
• Deprecated EVP_PKEY_ASN1_METHOD-related functions.
• Optimised amisslmaster.library for size as it contains no speed critical code, whilst making the logic for opening the libraries easier to follow and maintain.
