Worked on the LedgerHQ/ledger-secure-sdk repository to deliver cryptographic hardening and code quality improvements in C. Focused on strengthening security across signing and key-exchange primitives, the work addressed critical edge cases such as BIP0340 nonce handling, ECDH point validation, PSS salt-length enforcement, PKCS#1 v1.5 decode error propagation, and AES-GCM tag length validation. These enhancements reduced exploitable risk and improved error handling in cryptographic operations. Additionally, code formatting and readability were improved in cx_ecschnorr.c to ensure maintainability and clang-format compliance. The contributions emphasized robust security engineering, software maintenance, and adherence to cryptographic standards without impacting performance.

Mar 1, 2026March 2026: LedgerHQ/ledger-secure-sdk delivered substantial cryptographic hardening and code quality improvements. Key security hardening across signing and key-exchange primitives fixed critical edge cases and reduced exploitable risk: BIP0340 nonce handling and signature length checks, ECDH point validation, PSS salt-length enforcement, PKCS#1 v1.5 decode error propagation, and AES-GCM tag length validation. In addition, a code quality initiative improved readability and clang-format conformance in cx_ecschnorr.c, enhancing maintainability. These changes strengthen the platform’s trust, resilience, and compliance with cryptographic standards while preserving performance and reliability.
