# circom-dl

circom-dl is a a library implementing zk cryptographic primitives.

Currently, it supports:

- *bitInt* arithmetic. Used to implement operation of field that is larger than the field size of the underlying curve (e.g. bn128).

- *ec* arithmetic. Weierstrass elliptic curve over prime field operations. Non supported Weierstrass curves over prime field can be easily added by following instructions in curve.circom. Currently supports:

    - brainpool224r1

    - brainpoolP256r1

    - brainpoolP320r1

    - brainpoolP384r1

    - brainpoolP512r1

    - secp192r1

    - secp224r1

    - secp256r1

    - secp256k1

    - secp384r1

    - secp521r1

    - *to be continued*

- *babyjubjub* arithmetic. Used for curve with the same field as circom field (subgroup of bn128).

- *hasher*. Implemets different hash functions. Currently supports:

    - SHA1

    - SHA224

    - SHA256

    - SHA384

    - SHA512

    - Keccak256

    - Poseidon

    - *to be continued*

- *signatures*. Implemets different signature schemes. Currently supports:

    - ECDSA (on supported curves ^)

    - RSA with Pkcs1v15 padding for any field size, supported hash functions (Only sha1 and sha2-256 for now) and any exponent

    - RSA-PSS

        - SHA384 && SALT_LEN == 48

        - SHA256 && SALT_LEN == 64

        - SHA256 && SALT_LEN == 32

        - SHA512 && SALT_LEN == 64

    - *to be continued*

- *eth*. Impements exracting eth address from public key.

- *float*. Implements fixed point float numbers.  Currently supports:

    - Multiplication (both with and without ceiling)

    - Inverse

    - Exp

    - Switch precision.

- *matrix*. Implements matrix arithmetic. Currently supports:

    - Multiplication

    - Scalar multiplication

    - Hadamard product

    - Addition

    - Transposition

    - Determinant

    - Matrix Power

- *utils*. Some helper templates to make some base operations easier. Currently supports:

    - Switcher

- *int*. Implements some int arithmetic for nums < underlying field(e.g. bn128). Currently supports:

    - Inverse

    - Log

    - Sum of n elements

    - Other templates can be unsecure, never use them in produnction!
