gimli
A Java implementation of the Gimli cryptographic permutation and hash algorithm:
Gimli is a 384-bit permutation designed to achieve high security with high performance across a broad range of platforms, including 64-bit Intel/AMD server CPUs, 64-bit and 32-bit ARM smartphone CPUs, 32-bit ARM microcontrollers, 8-bit AVR microcontrollers, FPGAs, ASICs without side-channel protection, and ASICs with side-channel protection.
In conforms to the test vectors produced by the reference C implementation. N.B: The test vectors for the hash algorithm are incorrect and this implementation conforms to the corrected test vectors.
