大家好,又见面了,我是你们的朋友全栈君。
没想到被Android里的RSA加密折腾了几个小时,主要还是自己对RSA加密的原理不了解,然后网上相关的资料也少。
使用AndroidUtilCode工具类中的EncryptUtils.encryptRSA()
加密后的数据怎么也不对,后来自己找了段加密代码,才总算是可以了,这里记录一下。
首先我们需要先 生成一个RSA的公钥和私钥。
RSA加密公钥
代码语言:javascript复制-----BEGIN PUBLIC KEY-----
MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDOCSZxJyD9BCPF E0AwT1v/qdv
lMhLKkNbnp1BIrh9bnfuv15mULugWq7ARtWtppZVLHu7H0No6vZQRN66BY3wWbll

xpr5Okdai0szIb/EvwIDAQAB
-----END PUBLIC KEY-----
RSA加密私钥
代码语言:javascript复制-----BEGIN PRIVATE KEY-----

-----END PRIVATE KEY-----
然后附上RSA加密相关的代码
代码语言:javascript复制fun main(){
val idCard = "12345678"
val result = rsaEncode(idCard)
Log.i("Z-MMM", "result:$result")
}
fun rsaEncode(str: String): String? {
val publicKey = "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDOCSZxJyD9BCPF E0AwT1v/qdv
lMhLKkNbnp1BIrh9bnfuv15mULugWq7ARtWtppZVLHu7H0No6vZQRN66BY3wWbll
NPZP2Qg2xV3ubXcDa5CtfdmDbPeN Ol4s97Gzcn7VL1 3NXzMRLAm1E64hqkrMfE
xpr5Okdai0szIb/EvwIDAQAB"
var outStr = ""
try {
// base64编码的公钥
val decoded: ByteArray = Base64.decode(publicKey, Base64.DEFAULT)
val pubKey = KeyFactory.getInstance("RSA")
.generatePublic(X509EncodedKeySpec(decoded)) as RSAPublicKey
// RSA加密
val cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding")
cipher.init(Cipher.ENCRYPT_MODE, pubKey)
outStr = Base64.encodeToString(
cipher.doFinal(str.toByteArray(charset("UTF-8"))),
Base64.DEFAULT
)
} catch (e: Exception) {
e.printStackTrace()
}
return outStr
}
打印的结果
代码语言:javascript复制mAHc2ZtZuzDrA295Aw4CpYhctlJA3NeC7xd0BgGRMVSzBL8WRYuxNiDK1CQXuQ7B/3wgqH72CbRw

ras每次加密的结果都会变
验证加密结果 : 通过该网站我们可以对其进行解密,可以看到解密后的结果是12345678
感谢 Android RSA加密(Java后台给出公钥)
