#Ciphers-speed
Encryption speed comparison of 64-bit Linux optimized software implementation of block ciphers (ECB mode, several times reencryption of 1 GB RAM block with different data):
- Kalyna (Ukrainian national standard DSTU 7624:2014), all variants of block and key length;
- AES (FIPS-197), 128 and 256 key length;
- GOST 28147-89;
- BelT (Belarussian standard STB 34.101.31-2011);
- Kuznyechik (128-bit block cipher from the draft standard of Russia).
