Question

我是加密新手，我收到了这些说明

使用RSA算法，并使用PKCS＃1.5 padding（不是OAEP），并将结果添加到加密流中 - 这将成为加密密码。“我的代码中的字符串os是公钥。

我进口了一些罐子; org-apache-commons-codec.jar和bcprov-jdk15-130.jar。

由于某些原因，我在此行System.out.println("\n"+ "\n" +"encryptionresult" + "\n" + "\n" + Base64.toBase64String(cipher.doFinal(initiatorpassword.getBytes())) + "\n");

上收到错误

错误仅在整个字符串上突出显示toBase64String。

错误：“无法找到符号方法toBase64String。”

Answer 1

您正在寻找的方法是

<强> org.bouncycastle.util.encoders.Base64.encode(byte[] data)

我不确定您在哪里获得对Base64.toBase64String的引用，但快速搜索显示它与类似的C＃方法非常接近。

Answer 2

我猜你必须使用如下的方法并检查它是否编译

Base64.getEncoder().encodeToString(cipher.doFinal(initiatorpassword.getBytes()))

如何使用RSA算法加密密码？
