1、X.509标准 x509是由国际电信联盟(ITU-T)制定的数字证书标准；包含公钥和用户标志符、CA等； x509是数字证书的规范，P7和P12是两种封装形式；X.509是常见通用的证书格式。所有的证书都符合为Public key Infrastructure 制定的ITU-T x509国际标准。 PKCS # 7常用的后缀是： P7B， P7C， SPC PKCS # 12常用的后缀有： P12 ，PFX X．509 DER编码（ASCII）的后缀是： DER CER CRT X．509PEM编码（base64）的后缀是：PEM CER　CRT pem格式是经过base64编码的证书，der格式是DER编码的证书； 证书入和导出操作支持四种文件格式。 个人信息交换 (PKCS #12) 个人信息交换格式（PFX，也称为 PKCS #12）支持安全存储证书、私钥和证书路径中的所有证书。PKCS #12 是唯一可用于导出证书及其私钥的文件格式。 加密消息语法标准 (PKCS #7) PKCS #7 格式支持存储证书和证书路径中的所有证书 DER 编码的二进制 X.509 区别编码规则 (DER) 格式支持存储单个证书。该格式不支持存储私钥或证书路径。 Base64 编码的 X.509 Base64 格式支持存储单个证书。该格式不支持存储私钥或证书路径。 cer/crt证书：

I was wondering how do I solve this problem. I generate RSA-OAEP keypair using WebCrypto API, then I export private key in pkcs8 from the keypair which exports as ArrayBuffer and I want to encode this ArrayBuffer into base64 so I can store it as a PEM. In this testing example I am exporting key as pkcs8 and importing this pkcs8 back to CryptoKey. The problem is that sometimes it works and sometimes it does not. These are results of the code: NOTE: Only happens one of these states not all at once. NOTE2: This example does not contain -----BEGIN PRIVATE KEY----- prefix and suffix I am only

I have a PEM encoded Elliptic Curve public key that I'm trying to load into Bouncy Castle and everything I tried so far is failing. This is an example of the key I'm trying to load: -----BEGIN PUBLIC KEY----- MIGbMBAGByqGSM49AgEGBSuBBAAjA4GGAAQBhsFCcWY2GaiN1BjPEd1v+ESKO6/0 D0sUR4y1amHnOr3FZx6TdqdoSBqxownQrnAKGCwagGxUb7BWwPFgHqKQJHgBq+J7 F+6m5SKAEL1wS5pqya91N7oudF3yFW8oZRE4RQRdSLl3fV2aVXKwGDXciwhUhw8k x5OS4iZpMAY+LI4WVGU= -----END PUBLIC KEY----- It is generated by NodeJS Crypto module and the curve name is secp521r1. It's later on encoded into PEM by the npm package key-encoder . I already

This question is related to Opening and checking a Pem file in SWI-Prolog Once I have downloaded and opened the certificates how do I verify the signature chain? I have: :-use_module(library(http/http_client)). url('https://s3.amazonaws.com/echo.api/echo-api-cert-4.pem'). url_data1(Url,Certs):- http_open(Url,Stream,[]), all_certs(Stream,Certs), forall(member(C,Certs),my_validate(C)), close(Stream). all_certs(Stream,[C1|Certs]):- catch(load_certificate(Stream,C1),_,fail), all_certs(Stream,Certs),!. all_certs(_Stream,[]). my_validate(C):- memberchk(to_be_signed(Signed),C), memberchk(key(Key),C),

I'm trying to use the WinCrypt API in C++. My application need to cipher, decipher, sign and verify files, and I know how to do that once I have the correct keys. But my problem is actually that that is NOT the same application which generates those keys. What I have is public and private keys in files in PEM format : -----BEGIN RSA PRIVATE KEY----- [Base64 encoded] -----END RSA PRIVATE KEY----- And : -----BEGIN RSA PUBLIC KEY----- [Base64 encoded] -----END RSA PUBLIC KEY----- After some research, I have found how to import the public key : here and here , using the following methods :
