我想使用java用RSA公钥加密DSA密钥。但是,当我这样做时,我会得到以下错误:
javax.crypto.IllegalBlockSizeException: Data must not be longer than 245 bytes
at com.sun.crypto.provider.RSACipher.doFinal(RSACipher.java:337)
at com.sun.crypto.provider.RSACipher.engineDoFinal(RSACipher.java:382)
DSA和RSA密钥大小分别设置为1024和2048。我知道,使用RSA,我们不
我尝试过其他帖子中的建议,但它们对我没有帮助。当我通过java -jar -BigJar.jar运行我的jar时,我收到了异常:
Exception in thread main java.lang.SecurityException: no manifest section for signature fil entry edu/iris/Pissures/IfSeismogramMgr/MotionVectorAttributeHelper.class
我的ant文件是
<project name="USGS VHP" default="help" b
我正在尝试使用以下命令生成一个新的键区
ssh-keygen -t rsa -f id_rsa
根据手册,-t参数应该指示键的格式:
ssh-keygen [-q] [-b bits] [-t dsa | ecdsa | ed25519 | rsa] [-N new_passphrase] [-C comment] [-f output_keyfile]
[...]
The type of key to be generated is specified with the -t option. If invoked without any arguments, ssh-keygen will
有人知道我会怎么把这段java代码转换成python吗?
/**
* signs the data for the account account
*/
private byte[] sign(String pkStr,byte[] data, String keyType) throws Exception {
BASE64Decoder decoder = new BASE64Decoder();
KeyFactory keyFac = null;
//instantiate the key factory based on the key alg type
该错误遵循"ntp_crypto.c:2248:2: error:未知类型名称'DSA_SIG';您的意思是‘ECDSA_SIG’吗?“
make失败的输出如下:
tp_crypto.c: In function 'crypto_alice':
ntp_crypto.c:2188:13: warning: implicit declaration of function 'EVP_PKEY_get0_DSA'; did you mean 'EVP_PKEY_get0_RSA'? [-Wimplicit-function-
出于测试目的,我希望在我的服务器上启用DSA身份验证(让我们将其命名为A)。如果我删除位于/etc/ssh下的所有密钥对,则在sshd重新启动时生成RSA和DSA密钥对。
其结果是,如果我试图打开服务器B到此服务器A的SSH连接,将显示以下消息:
The authenticity of host '...' can't be established.
RSA key fingerprint is ...
Are you sure you want to continue connecting (yes/no)?
您知道如何禁用RSA身份验证,以便我的服务器B使用DSA在
我有:
x509证书(Base64);
字符串数据;
字符串数据签名(Base64)。
可以检查签名吗?
我的代码:
bool valid = false;
var signature = Convert.FromBase64String(base64Signature);
var data = Encoding.UTF8.GetBytes(stringData);
var x509 = new X509Certificate2(Convert.FromBase64String(certificate));
var dsa = x509.Public
我尝试通过执行以下命令来创建ssh密钥:
ssh-keygen -t dsa
然后它会提示我输入存储路径:
Enter file in which to save the key (/Users/KesongXie/.ssh/id_dsa): id_dsa
在输入密码短语后,我得到了以下结果
Your identification has been saved in id_dsa.
Your public key has been saved in id_dsa.pub.
然后,我尝试使用以下命令加载我的ssh私钥
ssh-add /Users/KesongXie/.ssh/id_dsa
它显
