A set of high-level APIs over PointyCastle for two-way cryptography.
Looking for password hashing? Please, visitpassword.
You can generate cryptographically secure random keys and IVs for you project.
Activate the encrypt package:
pub global activate encrypt
Then use thesecure-random command-line tool:
$ secure-randomCBoaDQIQAgceGg8dFAkMDBEOECEZCxgMBiAUFQwKFhg=
You can set the length and the base output.
$ secure-random --help-l, --length The length of the bytes (defaults to"32")-b, --base Bytes represented as base 64 or base 16 (Hexdecimal) (defaults to"64")-h, --[no-]help Show thishelp message
Current status is:
- AES with PKCS7 padding
- RSA with PKCS1 and OAEP encoding
- Salsa20
- SHA256 with RSA
import'package:encrypt/encrypt.dart';voidmain() {final plainText='Lorem ipsum dolor sit amet, consectetur adipiscing elit';final key=Key.fromUtf8('my 32 length key................');final iv=IV.fromLength(16);final encrypter=Encrypter(AES(key));final encrypted= encrypter.encrypt(plainText, iv: iv);final decrypted= encrypter.decrypt(encrypted, iv: iv);print(decrypted);// Lorem ipsum dolor sit amet, consectetur adipiscing elitprint(encrypted.base64);// R4PxiU3h8YoIRqVowBXm36ZcCeNeZ4s1OvVBTfFlZRdmohQqOpPQqD1YecJeZMAop/hZ4OxqgC1WtwvX/hP9mw==}
Default mode is SICAESMode.sic, you can override it using themode named parameter:
final encrypter=Encrypter(AES(key, mode:AESMode.cbc));
- CBC
AESMode.cbc - CFB-64
AESMode.cfb64 - CTR
AESMode.ctr - ECB
AESMode.ecb - OFB-64/GCTR
AESMode.ofb64Gctr - OFB-64
AESMode.ofb64 - SIC
AESMode.sic
To remove padding, passnull to thepadding named parameter on the constructor:
final encrypter=Encrypter(AES(key, mode:AESMode.cbc, padding:null));
