Installation #

``js
const encNdesc = require('crypto-data');
`

Usage #

FI DATA ENC N DESC ##

Note: all functions promised based functions so either you can use await or then to handle the response.

#### FIU Generate ECDH keys ####
`js
let ECDHkeypair= await encNdesc.enc.generateKeyMaterial(eccUrl);
/**
* eccUrl = ECC base Url [default is http://localhost:8111]
*/
`

#### FIP Encryption ####
`js
let encryptedData=await encNdesc.FIPEncryption(id, Data, fiuKeyMaterialData, eccUrl);
/**
* id= fip ID
* Data= FI Data
* fiuKeyMaterialData= his KeyMaterial
* eccUrl = ECC base Url
*/

Note : we can use all Encryption functions calling by encNdesc.enc
`


#### FIU Decryption ####
`js
let decryptedFIUData=await encNdesc.dataDecrypt(cipher,hisKeyMaterial, myScrtKey,fiuNonce, eccUrl);
/**
* cipher= encrypted Data
* fiuKeyMaterialData= his KeyMaterial
* myScrtKey= my ECDH privateKey
* fiuNonce = my random 32-byte BASE64 string
* opts = optional parameters Object
*/
Note : iv id depricated. need not pass iv as params inrenally it will took from cipher.

#### Version release summary
1. ##### 0.0.1
1. this is extracted from finpro-crypto v0.0.14
2. ##### 0.0.2
1. now onwards random nonce are integers only
3. ##### 0.0.3
1. in FIPEncryption return object the params key is changed from object to empty string.
4. ##### 0.0.4
1. revereted number nonce to Base64 encoded.
2. Introduced ECC API Services for ECDH Key Pair, FI Data Encryption and Decryption. Deprecated the curve25519-n library.
3. need to pass eccUrl as extra param for encryption , generate ecdh functions.
5. ##### 0.0.5
1. ECC docker version changed.
6. ##### 0.0.6
1. FI DB Data getting OoB now changed to AoB before doing Asnyc operations.
7. ##### 0.0.7
1. unused libraries are removed from .json file.
8. ##### 0.0.8
1. getting extra spaces after decryption for Encrypted FI. now its resolved. now it will work for both JSON and XML.
....
....
13. ##### 0.0.13
1. upgrading ECC service from v1 to v1.2. made changes in functions as per new ecc API's request and responses.
16. ##### 0.0.16
1. in encryption previously we are passing base64 FI data now plain text with stringified is enough.
17. ##### 0.0.17
1. in above encryption technique XMl string is stringfiying twice so implemented logic based typeof method stringifying.
18. ##### 0.0.18
1. DHPublickey expiry time formate currently accepting Z only now we made changes to accept both Z and +0000 as suffix.
19. ##### 0.0.19
1. keymaterials sequence
