How to symmetric encrypt a file in GPG?
For example to encrypt a file called file.txt using this cipher, use: gpg –symmetric –cipher-algo AES256 file.txt This will produce file.txt.gpg containing the encrypted data. You can call the resulting file whatever you like by using the -o (or –output) option.
How to encrypt a 256 bit file in GPG?
To encrypt data using 256 bit AES, use the –cipher-algo AES256 option. For example to encrypt a file called file.txt using this cipher, use: gpg –symmetric –cipher-algo AES256 file.txt. This will produce file.txt.gpg containing the encrypted data. You can call the resulting file whatever you like by using the -o (or –output) option.
How to encrypt a file in GPG using TwoFish?
For example to encrypt a file called file.txt using this cipher, use: This will produce file.txt.gpg containing the encrypted data. You can call the resulting file whatever you like by using the -o (or –output) option. To decrypt file.txt.gpg or whatever you called it, run: Twofish has a block size of 128bits.
Which is the best encryption algorithm for GPG?
Below, we’ll cover several of the available ciphers including: AES256, TWOFISH, and CAMELLIA256. To see a list of available ciphers, run
How to generate symmetric and asymmetric encryption keys?
We are using Beaglebone Black based custom board, and want to use hybrid encryption for encrypting firmware file, i.e. symmetric for encryption big firmware file and asymmetric for encrypting symmetric key file. I refer to this blog for hybrid encryption idea.
How can I automate GPG decryption which uses a…?
Automating decryption means you have to store the passphrase somewhere, or not use a passphrase (unless you use additional options as pointed out in the other answer submitted by Stephen while I was typing mine)! Neither of those match your requirement for good or great security standards.
