How to use the wolfSSL staticmemory feature
wolfSSL is an embedded cryptographic library that includes a TLS/DTLS implementation. For resource-constrained devices or safety-critical applications, dynamic memory allocation via malloc and free system calls may be unavailable. To address these scenarios, wolfSSL offers the –enable-staticmemory feature. This feature provides a robust and straightforward allocation mechanism as an alternative. It utilizes a pre-allocated buffer, […]

Many developers working on FreeBSD, OpenBSD, and NetBSD may not realize that cURL can be integrated with wolfSSL for secure communications. This combination allows applications to use modern TLS protocols and FIPS 140-3 validated cryptography on BSD platforms. Secure communication is critical in servers and embedded devices. Using wolfSSL with cURL ensures standards-compliant TLS connections […]

The Radio Equipment Directive (RED) 2014/53/EU establishes the regulatory framework for placing radio equipment on the European market. Its goal is to create a unified market while ensuring essential requirements for safety, electromagnetic compatibility, efficient use of the radio spectrum, and more recently cybersecurity and data protection. To strengthen protections, the European Commission activated Articles […]
Read MoreMore TagSupport for STM32U5 DHUK
In wolfCrypt and wolfPKCS11 we added support for using a Derived Hardware Unique Key (DHUK) for AES with the STM32U5. This feature enables use of a device unique AES key (up to 256-bit) available for encryption/decryption. The key cannot be read from the hardware, which makes it great to wrap other symmetric keys for storage […]

Recent commits to wolfSSL have enabled support to decode new CMS/PKCS#7 message types. The CMS message type EncryptedKeyPackage (defined in RFC 6032) can be decoded with the new API wc_PKCS7_DecodeEncryptedKeyPackage(). The CMS message types SymmetricKeyPackage and OneSymmetricKey (defined in RFC 6031) can be decoded with the new APIs wc_PKCS7_DecodeSymmetricKeyPackageAttribute(), wc_PKCS7_DecodeSymmetricKeyPackageKey(), wc_PKCS7_DecodeOneSymmetricKeyAttribute(), and wc_PKCS7_DecodeOneSymmetricKeyKey(). If you […]

Read MoreMore TagRelaxing CMS/PKCS#7 decode support requirements
Previous wolfSSL versions required X.963 KDF support and AES keywrap functionality to be enabled in order to build CMS/PKCS#7 decode support. Recent changes to wolfSSL have allowed CMS/PKCS#7 decode support to be built without either of these requirements. Previously, if the user desired to have the HAVE_PKCS7 build option defined, then the HAVE_X963_KDF and HAVE_AES_KEYWRAP […]
