Read an encrypted private key with bouncycastle/spongycastle

阅读更多关于 Read an encrypted private key with bouncycastle/spongycastle

问题 I have a password protected, encrypted RSA private key, which was created with PyCrypto (2.6.1) and has according to their docs the following format: PrivateKeyInfo, PKCS#8 (DER SEQUENCE), PEM (RFC1423) , see [https://www.dlitz.net/software/pycrypto/api/current/Crypto.PublicKey.RSA._RSAobj-class.html#exportKey]. How can I decrypt this RSA key with Bouncycastle/Spongycastle? I've searched Google for quite a long time and only came up with results, that either won't work with version 1.50

I'm trying to find a way to read a privateKey created using OpenSSL PKCS#8 RSA in C# without use external library. Does Someone know how i can do this? The easiest way to do this with an external library, is using the (free) Chillkat Public / Private Key Component : using that, importing the key can be done using just a few lines of code and if you're willing to pay the $149 or so for the rest of the library, it will make dealing with general crypto concepts a lot easier as well. And unlike the regular Microsoft .NET Framework, the Mono project does seem to have a PKCS8 implementation for

PKCS#1 and PKCS#8 format for RSA private key [closed]

Can some one help me understand how an RSA key literally is stored in these formats? I would like to know the difference between the PKCS formats vs Encodings(DER, PEM). From what I understand PEM is more human readable. Is PEM/DER for keys/certs similar to UTF-8/16 for characters? What is the significance of DER/PEM? Sorry too many questions but fed up googling and getting vague answers. Thanks. Luke Joshua Park PKCS#1 and PKCS#8 (Public-Key Cryptography Standard) are standards that govern the use of particular cryptographic primitives, padding, etc. Both define file formats that are used to

问题 I have private key stored in file in PKCS8 DER format and protected by password. What is the easiest way to read it? Here is the code I use to load unencrypted one: InputStream in = new FileInputStream(privateKeyFilename); byte[] privateKeydata = new byte[in.available()]; in.read(privateKeydata); in.close(); KeyFactory privateKeyFactory = KeyFactory.getInstance("RSA"); PKCS8EncodedKeySpec encodedKeySpec = new PKCS8EncodedKeySpec(privateKeydata); PrivateKey privateKey = privateKeyFactory

Load PKCS#8 binary key into Ruby

问题 I'm trying to load a particular private key encoded in binary DER format ( PKCS#8 ) into Ruby. However, OpenSSL::PKey won't recognize it. I can make it work by doing some console work and transforming it into a PEM like so: openssl pkcs8 -inform DER -in file.key -passin pass:xxxxxxxx >private_key.pem After this, the key can correctly be read. However, since I would like for the whole process to be done in memory instead of writing and reading files. So my question is: Is it possible to load
