pem

问题 I'm having .crt and .pem file with -----BEGIN CERTIFICATE----- MIIFSDCCBDCg........................................ -----END CERTIFICATE----- and I want RSA key from this file. anyone is having any idea that how we can do that. I have used below command one by one openssl rsa -in XXX.crt -out input1.der -outform DER openssl rsa -in input1.der -inform DER -out key.pem -outform PEM But, It gives error: unable to load Private Key 140331982231200:error:0906D06C:PEM routines:PEM_read_bio:no start

问题 We require client authentication to send a RESTful request to some of our web services. I've installed a client cert (.pem) and key on the my local mac os via the key tool. These are not self signed. openssl pkcs12 -export -name myservercert -in not_self_signed.crt -inkey server.key -out keystore.p12 ...and converted to JKS format keytool -importkeystore -destkeystore mykeystore.jks -srckeystore keystore.p12 -srcstoretype pkcs12 -alias myservercert I'm trying to build a Java client to do the

问题 This is how I generate public/private key pair var statusCode: OSStatus var publicKey: SecKey? var privateKey: SecKey? let publicKeyAttribute: [NSObject : NSObject] = [kSecAttrIsPermanent: true as NSObject, kSecAttrApplicationTag: "publictag".data(using: String.Encoding.utf8)! as NSObject] let privateKeyAtrribute: [NSObject: NSObject] = [kSecAttrIsPermanent: true as NSObject, kSecAttrApplicationTag: "privatetag".data(using: String.Encoding.utf8)! as NSObject] var keyPairAttr = [NSObject: Any]

问题 I need to make a software activation mechanism. So i ended up with this scheme: App creates a unique id, based on computer's hardware. Buyer emails this id to me. I sign it with my private key and i send back the signed string. App verifies string (decodes it with contained public key and compares it with hardware id). So far i am done with hardware id and i have created the keys (1024bit) with openssl, that's two files private.pem and public.pem. I worked with some code provided by msdn, but

问题 JKJS Observations: Suppose RSA private key is created by following commands: openssl genrsa -out mykey.pem 1024 Then, there is no problem reading key from that file in C: RSA *privatekey=NULL; privatekey=PEM_read_RSAPrivateKey(fp,NULL,NULL,NULL); if(privatekey==NULL) ERR_print_errors_fp(stderr); But, if RSA keypair is created by following command: openssl req -newkey rsa:1024 -sha1 -keyout mykey.pem -out rootreq.pem Then reading from mykey.pem results in error. Why? JKJS Hardik 回答1: In the

问题 I have gone through many similar threads but no luck!! I want to generate public and private keys using a PEM file. Following is the code I am using for the same: String pemFileNme = "C:\\Users\\amitmm\\Desktop\\clean\\key.pem"; File pubKeyFile = new File(pemFileNme); File privKeyFile = new File(pemFileNme); // read public key DER file DataInputStream dis = new DataInputStream(new FileInputStream(pubKeyFile)); byte[] pubKeyBytes = new byte[(int)pubKeyFile.length()]; dis.readFully(pubKeyBytes)

问题 i received the following from some legacy system when i asked for private key: MODULUS, PUBLIC EXP, PRIVATE EXP, PRIME_P, PRIME_Q, PARAM_P, PARAM_Q, Q_MOD_INV All of this data is in hex, how can i convert this to a openssl PEM file or PFX ? Thank you and best regards! 回答1: Generate RSA key with openssl: openssl genrsa -out rsa.pem 2048 Convert RSA key from PEM format to DER format: openssl rsa -inform PEM -in rsa.pem -outform DER -out rsa.der Open file rsa.der in ASN.1 Editor: ASN.1 structure

问题 I have a function that need RSA encryption/decryption. With provided .pem file, that contains pair key for RSA. By using Org.BouncyCastle as same as How to read a PEM RSA private key from .NET; or using the method in http://www.jensign.com/opensslkey/opensslkey.cs. What i received is "bad data" with parameter DQ has 63 byte (different from 64 byte). (the .pem file is said that been fine.) Is there any problem here? 回答1: All RSA parameters are simply (huge) numbers. Most of them will have

问题 I have this code to generate a CER file using the alias: public class TestFromAliasToCER { public static final int KEY_SIZE = 1024; public static final String BEGIN_CERT = "-----BEGIN CERTIFICATE-----"; public static final String END_CERT = "-----END CERTIFICATE-----"; public final static String LINE_SEPARATOR = System.getProperty("line.separator"); public static void main(String[] args) throws FileNotFoundException, IOException, NoSuchAlgorithmException, NoSuchProviderException,

问题 This question already has an answer here : Use OpenSSL RSA key with .Net (1 answer) Closed 2 years ago . I'm trying to generate a private RSA key with openssl, which works fine so far. I'd like to get the format of the key in PEM. When writing the key into a file the format seems to be fine but when I save the key in PEM in a char array than it seems to differ from the one written to the file!? Here is a short example compiled with: #include <iomanip> #include <string> #include <string.h>
