Kernel Hacking – use crypto API in the IRQ context
After my first post about Linux kernel crypto API, I keep playing with kernel crypto API for DSA and RSA implementations (will talk about these in my future posts). The truth is crypto API is NOT designed for IRQ context. … Continue reading
Hack Go – generate non-FIPS DSA key parameters using hacked Go compiler
Common DSA key parameter generation follow FIPS 186-3, which requires (L, N) bits length for P and Q, where L is at least 1024 and N is at least 160. However, sometimes we may want non-FIPS (L, N), for example, … Continue reading
crypto – use Linux kernel crypto API
Crypto is an important part of the Linux kernel source code. One can tell from the standalone crypto directory under the kernel source tree. Device drivers, file system and security all need crypto. This post does not help understand the … Continue reading
