+## SMS4 Sub-Library of GMSSL
+
+Encryption modes:
+
+ * ECB: encrypt or decrypt a block, process only one block per call.
+ * CBC: process variable length input with zero padding, IV works as both input and output.
+ * CFB: same as CBC
+ * OFB: same as CBC
+
+Optimization for specific architecture:
+
+ * AVX2: support ECB, CTR and CBC-decrypt (todo)
+ * KNC-NI: support ECB, CTR and CBC-decrypt (todo)
+
+Some future plans:
+
+ * more operation modes, GCM, XTS, FFX, OFB ...
+ * more optimiazations: ARM/NEON, X86 ASM, GPU, ...
+ * secure implementation: Bit Slicing, Timing attack ...
+ * formally verified.
