| Suppose you want to implement ECDH with NIST256 elliptic curve. First you need to initialize the context: |
| |
| ``` |
| var ctx = new CTX("NIST256"); |
| ``` |
| then you can call the functions as follows: |
| ``` |
| ctx.ECDH.KEY_PAIR_GENERATE(...); |
| ctx.ECDH.ECPSVDP_DH(...); |
| ``` |
| If you need to use more than one elliptic curve in the same script you only need to initialize two different contexts, for example |
| ``` |
| var ctx1 = new CTX("NIST256"); |
| var ctx2 = new CTX("C25519"); |
| ``` |
| The following is the list of all elliptic curves supported by MCJS |
| ``` |
| ['ED25519', 'C25519', 'C41417', 'GOLDILOCKS', 'NIST256', 'NIST384','NIST521', 'BRAINPOOL', 'ANSSI', 'HIFIVE', 'NUMS256W', 'SECP256K1' |
| 'NUMS256E', 'NUMS384W', 'NUMS384E', 'NUMS512W', 'NUMS512E', 'BN254', 'BN254CX', 'BLS383', 'BLS381', 'FP256BN', 'FP512BN', 'BLS461', 'BLS24', 'BLS48']; |
| ``` |
| |
| This library supports also RSA encryption/decryption and RSA signature. The following is a quick example on how to use RSA. First initialize the context |
| ``` |
| var ctx = new CTX("RSA2048"); |
| ``` |
| then you can call the RSA functions as follows: |
| ``` |
| ctx.RSA.ENCRYPT(...); |
| ctx.RSA.DECRYPT(...); |
| ``` |
| The following is the list of all the RSA security level supported by *MCJS* |
| ``` |
| ['RSA2048','RSA3072','RSA4096']; |
| ``` |
| |
| MCJS supports also SHA256, SHA384, SHA512, AES-GCM encryption and Marsaglia & Zaman random number generator. Those functions are contained in every context initialized with RSA or with an elliptic curve. If you want to create a context supporting only those general functions then initialize it with no parameter as follows: |
| ``` |
| var ctx = new CTX(); |
| ``` |
