I found a tutorial here but it requires both Secret Key and Public Key to encrypt data. However I’ve modified the codes a bit to only require public key (no signing, no compress) and thought I should publish it here in case anyone also looking for a solution for this question. Belows is the modified … Read more
Update Oct. 2018, as commented below by PHPirate: λ git –version git version 2.19.1.windows.1 λ gpg –version gpg (GnuPG) 2.2.9-unknown libgcrypt 1.8.3 Copyright (C) 2018 Free Software Foundation, Inc.

You can write a simple wrapper around GNU PGP which basically executes the GPG command from Java. The advantage of using GNU PGP is that you will not be tied to a specific library. The amount of documentation and support available online for third-party libraries is not as rich as other encryption schemes since most … Read more
Note: Adding the -S option all the time can be cumbersome. In git 2.0 and later, you can add a config which will take care of that option for you. See commit 2af2ef3 by Nicolas Vigier (boklm): Add the commit.gpgsign option to sign all commits If you want to GPG sign all your commits, you … Read more
You don’t need PyCrypto or PyMe, fine though those packages may be – you will have all kinds of problems building under Windows. Instead, why not avoid the rabbit-holes and do what I did? Use gnupg 1.4.9. You don’t need to do a full installation on end-user machines – just gpg.exe and iconv.dll from the … Read more
Looking at the source of PGPUtil you can see what API to call when working with streams or arrays directly: public static void writeFileToLiteralData(OutputStream out, char fileType, File file, byte[] buffer) throws IOException { PGPLiteralDataGenerator lData = new PGPLiteralDataGenerator(); OutputStream pOut = lData.open(out, fileType, file.getName(), new Date(file.lastModified()), buffer); FileInputStream in = new FileInputStream(file); byte[] buf … Read more
Incoming signatures always point to a UID. UIDs cannot be modified, only revoked. If you want to change one, it will have to get signed again. If you revoke a UID, you will lose all incoming signatures. UIDs are simple strings usually adhering to the pattern Name (comment) <mail@example.org>, and the signature is created over … Read more
Yes, you will need to transfer the keys. Mac and Linux work the same, storing the keys in ~/.gnupg. The safest way to transfer the files is using scp (part of ssh): scp -rp ~/.gnupg othermachine: However, you will need to have ssh working first. Transferring them with, say, a USB flash drive isn’t such … Read more
You get that error because you don’t have the public key of the person who signed the message. gpg should have given you a message containing the ID of the key that was used to sign it. Obtain the public key from the person who encrypted the file and import it into your keyring (gpg2 … Read more
