Microsoft Azure Linux Kernel Crypto API
Microsoft Corporation - FIPS 140 #4277
The Microsoft Azure Linux Kernel Crypto API Cryptographic Module is a general-purpose, software-based cryptographic module. The module provides general purpose cryptographic services that leverage FIPS 140-2-approved cryptographic algorithms. The module runs as part of the operating system kernel, provides cryptographic services to kernel applications through a C language Application Program Interface (API), and provides cryptographic services to user applications through an AF_ALG socket interface. The module is implemented as a set of shared libraries and binary files.
