Usage

Encrypt methods

import 'package:fast_rsa/fast_rsa.dart';

var result = await RSA.encryptOAEP(message, label, Hash.HASH_SHA256, publicKey)
var result = await RSA.encryptPKCS1v15(message, publicKey)

var result = await RSA.encryptOAEPBytes(messageBytes, label, Hash.SHA256, publicKey)
var result = await RSA.encryptPKCS1v15Bytes(messageBytes, publicKey)

Decrypt methods

import 'package:fast_rsa/fast_rsa.dart';

var result = await RSA.decryptOAEP(message, label, Hash.HASH_SHA256, privateKey)
var result = await RSA.decryptPKCS1v15(message, privateKey)

var result = await RSA.decryptOAEPBytes(messageBytes, label, Hash.SHA256, privateKey)
var result = await RSA.decryptPKCS1v15Bytes(messageBytes, privateKey)

Sign methods

import 'package:fast_rsa/fast_rsa.dart';

var result = await RSA.signPSS(message, Hash.SHA256, SaltLength.SALTLENGTH_AUTO, privateKey)
var result = await RSA.signPKCS1v15(message, Hash.SHA256, privateKey)

var result = await RSA.signPSSBytes(messageBytes, Hash.SHA256, SaltLength.SALTLENGTH_AUTO, privateKey)
var result = await RSA.signPKCS1v15Bytes(messageBytes, Hash.SHA256, privateKey)

Verify methods

import 'package:fast_rsa/fast_rsa.dart';

var result = await RSA.verifyPSS(signature, message, Hash.SHA256, SaltLength.SALTLENGTH_AUTO, publicKey)
var result = await RSA.verifyPKCS1v15(signature, message, Hash.SHA256, publicKey)

var result = await RSA.verifyPSSBytes(signatureBytes, messageBytes, Hash.SHA256, SaltLength.SALTLENGTH_AUTO, publicKey)
var result = await RSA.verifyPKCS1v15Bytes(signatureBytes, messageBytes, Hash.SHA256, publicKey)

Generate Methods

import 'package:fast_rsa/fast_rsa.dart';

var result = await RSA.generate(2048)

Convert Methods

import 'package:fast_rsa/fast_rsa.dart';

var result = await RSA.convertJWKToPrivateKey(data, keyId)
var result = await RSA.convertJWKToPublicKey(data, keyId)

var result = await RSA.convertKeyPairToPKCS12(privateKey, certificate, password)
var result = await RSA.convertPKCS12ToKeyPair(pkcs12, password)

var result = await RSA.convertPrivateKeyToPKCS8(privateKey)
var result = await RSA.convertPrivateKeyToPKCS1(privateKey)
var result = await RSA.convertPrivateKeyToJWK(privateKey)

var result = await RSA.convertPrivateKeyToPublicKey(privateKey)

var result = await RSA.convertPublicKeyToPKIX(publicKey)
var result = await RSA.convertPublicKeyToPKCS1(publicKey)
var result = await RSA.convertPublicKeyToJWK(publicKey)

var result = await RSA.encryptPrivateKey(privateKey, password, PEMCipher.PEMCIPHER_AES256)
var result = await RSA.decryptPrivateKey(privateKeyEncrypted, password)

Util Methods

import 'package:fast_rsa/fast_rsa.dart';

var result = await RSA.hash(message, Hash.SHA256)
var result = await RSA.base64(message)
