Recommendations for Java + OpenPGP?

由 心已入冬 提交于 2019-12-07 02:32:28
问题 I want to develop a small OpenPGP client and I'm searching for a Java library for OpenPGP. Are there any (open source) recommendations for this approach? Cryptix.org does not seem alive anymore... 回答1: I found the BouncyCastle library, for Java and C#. I haven't any experiences with it. I will try it and report here. It provides: A lightweight cryptography API for Java and C#. A provider for the Java Cryptography Extension and the Java Cryptography Architecture. A clean room implementation of

Getting BouncyCastle to decrypt a GPG-encrypted message

由 爱⌒轻易说出口 提交于 2019-12-06 08:27:20
问题 How can I get BouncyCastle to decrypt a GPG-encrypted message? I have created a GPG key pair at the CentOS 7 command line using gpg --gen-key . I chose RSA RSA as the encryption types, and I exported the keys using gpg --export-secret-key -a "User Name" > /home/username/username_private.key and gpg --armor --export 66677FC6 > /home/username/username_pubkey.asc I am able to import username_pubkey.asc into a remote Thunderbird client of another email account and successfully send an encrypted

Command line GPG decrypting using c# - passphrase?

由 ε祈祈猫儿з 提交于 2019-12-06 07:26:22
I'm using the command line to encrypt files that I am sending out but I am trying to figure out how to use the same method to decrypt them. If I run the command it get prompted for the passphrase, but I don't see a way to pass in the passphrase using the command line. Here is how I am encrypting the file: var proc = new Process(); proc.EnableRaisingEvents = false; proc.StartInfo.WorkingDirectory = "C:\\"; proc.StartInfo.FileName = @"C:\Progra~1\GNU\GnuPG\gpg.exe"; proc.StartInfo.Arguments = @"-e -u ""user1@example.com"" -r ""user2@example.com"" ""C:\file.csc"""; proc.Start(); proc.WaitForExit(

Python/POpen/gpg: Supply passphrase and encryption text both through stdin or file descriptor

由 烈酒焚心 提交于 2019-12-06 05:20:54
问题 I'm trying to remote control gpg through a python program via POpen . I have a file that contains encrypted data which I want to decrypt, modify and write back to disk re-encrypted. Currently I am storing the decrypted information in a temporary file (which I shred when the program ends). Then I perform my modifications to that file and then re-encrypt it using a function, which pipes the passphrase through stdin . The code for this is as follows: def encrypt(source, dest, passphrase, cipher

Batch encrypt with public key using Gpg4win command line

We are setting up our first EDI system that relies on incoming and outgoing file encryption using OpenPGP. The incoming files that are encrypted with our public key, we can successfully decrypt using our private key using Gpg4win's command line option: gpg --batch --passphrase "SOME_KEY" --decrypt-files "%decryptingdir%\*.pgp" What I now need to do, is the reverse, and encrypt the outgoing files using our partners public key. I have been unable to find any command line documentation around batch encryption using a public key. I assumed it would be something in the order of: gpg --batch -

GPG signing Git commits after updating MacOSX hangs on password entry

由 余生长醉 提交于 2019-12-05 22:24:33
I think this started happening after I updated the lastest OSX version, which might or might not have contained a new version of Git. But now, almost every time I try to sign my commits (either through git commit -S or git rebase -S ): I get the password prompt Enter the password Press enter and nothing happens. No 'Permission Denied: Invalid Password', nothing. I have to Ctrl-C to get out of the prompt. Not sure if this is a known issue on Git or El Capitan 10.11.6, but its getting vexing since I always sign my git commits. I've also checked that no other GPG processes are running and nothing
