wolfSSL releases a new product; wolfCOSE a zero alloc C embbedded COSE stack
wolfSSL has launched wolfCOSE, a lightweight C library designed for implementing COSE and CBOR. The library features zero dynamic allocation and a minimal footprint, making it suitable for embedded systems. It supports a wide range of cryptographic algorithms and is built on wolfSSL's crypto backend.
- ▪wolfCOSE implements all six COSE message types as defined in RFC 9052.
- ▪The library supports post-quantum signing with ML-DSA at three security levels.
- ▪It has a tiny footprint, with a minimal build requiring only 7.5 KB of .text.
