passphrase

I am trying to incorporate GPG clear-signing of text in a string in a PHP script. I can cause GPG to encrypt text in a string like this: $encrypted = shell_exec("echo '$text' | gpg -e -a -r foo@bar.com --trust-model always"); and that works perfectly, with the encrypted text being sent to the $encrypted variable. This proves GNUPGHOME and GNUPG are set up correctly. However, when I try to produce a clear-signed message in the same way with this: $text = "googar"; $signature = exec("echo $passphrase | gpg -v --clearsign --no-tty --passphrase-fd 0 '$text' 2>&1 1> /dev/null", $output); I am

title says it all. I was wondering how do I generate RSA key pair using WebCrypto API and how do I secure it with a passphrase so I can store it in a database. You can generate an RSA key pair with WebCrypto and export it as jwk (Json Web Key), pkcs#8 (private) or spki (public). See SubtleCrypto.exportKey() and the example code bellow To export the key to an external system in a protected way you could use an standard like: PKCS#8: The PKCS#8 private key format defined at IETF Public Key-Cryptographic Standard Encryption #8. allow encryption with a passphrase, but WebCryptography exportKey

I am having some difficulties with a git client written in java. I am using the jGit library to connect through ssh on the git server. The problem is that i don't know how to specify the path to the private key and the passphrase for it. I couldn't find any examples in the jGit documentation about what functions i need to call. From what i read the jGit library is using JSch to connect to the server using ssh and JSch supports private keys and passphrases. Does anyone have any experience with this or has some working code? Thank you I didn't ever use jGit, but from looking at the Javadocs

When I execute these commands (setting a passphrase, after the first)... $ ssh-keygen -t dsa $ chmod 600 my_key $ chmod 600 my_key.pub ...and then, to test the passphrase... $ ssh-add my_key.pub ...I keep getting: Bad passphrase, try again for my_key.pub: Bad passphrase, try again for my_key.pub: Bad passphrase, try again for my_key.pub: Bad passphrase, try again for my_key.pub: ... What am I doing wrong? You're trying to add public key to the agent, that one isn't pass-protected, the private one is. Try adding your private key and it should work. 来源： https://stackoverflow.com/questions

How do you generate passwords? Random Characters? Passphrases? High Ascii? Something like this? cat /dev/urandom | strings Mac OS X's "Keychain Access" application gives you access to the nice OS X password generator. Hit command-N and click the key icon. You get to choose password style (memorable, numeric, alphanumeric, random, FIPS-181) and choose the length. It also warns you about weak passwords. Arul S Use this & thumps up :) cat /dev/urandom | tr -dc 'a-zA-Z0-9-!@#$%^&*()_+~' | fold -w 10 | head -n 1 Change the head count to generate number of passwords. A short python script to

We receive GPG encrypted files from a third party. I'm modifying a C# program that finds the encrypted files, decrypts them, and deletes the encrypted ones. It all works except during the decryption part it prompts for a phassphrase; I know the passphrase and it works when entered. I need to pass the passphrase in the command so the prompt never appears. string CommandText = string.Format("echo {0}|gpg.exe --keyring {1} --secret-keyring {2} --batch --yes --passphrase-fd 0 -o {3} -d {4}", passPhrase, publicKeyRingPath, secretKeyRingPath, outputFullPath, encryptedFilePath); I have also tried:
