## Status of the implementation
- TFHE
- {TLWE, TGLWE, TLev, TGLev, TGSW, TGGSW} encryption & decryption
- addition of ciphertexts, addition & multiplication of ciphertext by a plaintext
- external products of ciphertexts
- TGSW x TLWE
- TGGSW x TGLWE
- TGSW & TGGSW CMux gate
- blind rotation, key switching, mod switching
- bootstrapping
- CKKS
- encoding & decoding
- encryption & decryption
- addition & substraction of ciphertexts
- BFV
- encryption & decryption
- addition & substraction of ciphertexts
- addition & multiplication of ciphertext by a plaintext
- multiplication of ciphertexts with relinearization
- GFHE (generalized FHE)
- {GLWE & GLev} encryption & decryption
- key switching, mod switching
- addition & substraction of ciphertexts
- addition & multiplication of ciphertext by a plaintext
- arith
- base arithmetic for $\mathbb{Z}_q,~~ R_q=\mathbb{Z}_q[X]/(X^N+1),~~ R=\mathbb{Z}[X]/(X^N+1),~~ \mathbb{T}_q[X]/(X^N +1)$
- NTT implementation (negacyclic convolution)
