Email with attachments and images signed with bouncycastle can't be verified by email client

阅读更多关于 Email with attachments and images signed with bouncycastle can't be verified by email client

问题 I have a MailComposer that builds a mime message and digitally signs the body part (content) using a MailSigningService . Signing is implemented in the sign() and buildSignedGenerator() methods. After receiving the mail, the mail client detects a signature but complains that the mail may have been tampered. The mail client is able to show the certificate, it shows all certificates (incl the CA). So, either the signing implementation based on Bouncycastle is not done properly or the message

OpenSSL C++ RSA sign is different from command line sign

阅读更多关于 OpenSSL C++ RSA sign is different from command line sign

问题 I'm trying to sign a text in C++ and then verify it in the command line. I'm using OpenSSL libraries. This is my command line for key generation: openssl genrsa -out key.pem 1024 Now I have my private key. Then this is how I do to sign in command line: echo "hola" | openssl rsautl -pkcs -sign -inkey key.pem > sign.txt At this point all works like it seems to be, now I have a sign in sign.txt. Now I'm trying to do the same in C... This is my code: RSA * rsaPrivKey; RSA * createRSAWithFilename

Securely store p12 file in rails

阅读更多关于 Securely store p12 file in rails

问题 How do I securely store my p12 file in rails? My production web app will be in Heroku. The file is used to sign some documents dynamically. 回答1: Storing the p12 contents in an environment variable should be sufficiently secure on Heroku. This way it's at least not available in your code base or through your database. You can setup Heroku environment variables like this: heroku config:add P12_CONTENTS="$(cat /path/to/file.p12)" 来源： https://stackoverflow.com/questions/12929065/securely-store

6-1 符号函数 (10分)

阅读更多关于 6-1 符号函数 (10分)

本题要求实现符号函数sign(x)。函数接口定义： int sign( int x ); 其中 x 是用户传入的整型参数。符号函数的定义为：若 x 大于0， sign(x) = 1；若 x 等于0， sign(x) = 0；否则， sign(x) = −1。裁判测试程序样例： #include <stdio.h> int sign( int x ); int main() { int x; scanf("%d", &x); printf("sign(%d) = %d\n", x, sign(x)); return 0; } /* 你的代码将被嵌在这里 */ 输入样例： 10 输出样例： sign(10) = 1 int sign(int x){ if(x>0){ return 1; }else if(x==0){ return 0; } return -1; } 来源： CSDN 作者： c_lanxiaofang 链接： https://blog.csdn.net/c_lanxiaofang/article/details/103469635

阅读更多关于 How to sign xml with X509 cert, add digest value and signature to xml template

问题 I am quite new to C# and especially new to Signing with X509. I have an xml template in which I have to add the certificate used (done) and sign the timestamp (TS-1), the binary security token and the body (id-1). Furthermore, I need to write (e.g. replace placeholders) with the digest value of these 3 elements and add the signature value. However, I do not really understand the concept, e.g. how to do this. I read a couple of websites, e.g. signing a xml document with x509 certificate but I
