I'm trying to encrypt file.
Here is my command.
"gpg --yes --batch --cipher-algo AES256 --passphrase abcd123 --output "+"E:/Softwares"+"/" +"logfile"+".gpg --symmetric --cipher-algo AES256 "+"E:/Softwares/logfile.txt"
But am getting error like this:
java.io.IOException: Cannot run program "gpg": CreateProcess error=2, The system cannot find the file specified
at java.lang.ProcessBuilder.start(Unknown Source)
Please anyone can help me what's going on?
I've used this command earlier to do encryption as well. but this time its giving problem.
Thanks !!

Am trying to decrypt an encrypted file, I have all the keys in place (secret and public), I don't know why its not generating output file. Following are the commands am running. I know there are several post already there but I cant refer them until and unless any error flashes on my command prompt.
gpg --list-secret-keys
Its listing secret keys
gpg --list-keys
Its listing all keys
gpg --import "c:\folder_location\name_PublicKey.gpg"
successfully imported keys
gpg --batch --yes --passphrase my_passphrase --local-user "mycomp name
" -o "c:\folder_location\filenameTEST.txt" -d
"c:\folder_location\ENCRYPTEDFILE.txt.gpg"
Am not able to decrypt file on command line, There is no error reported on command prompt. Command remains Active all the time, needed force close.
Anything am missing here to check? any suggestions?
There was no issue with my command, actual problem was CR and LF control characters (new line). When I removed those characters, decryption worked without any errors! GPG never detected these characters and statement got parsed without any error, and later command froze without any error/output.
I am currently writing a batch script to automate signing and encrypting files, on GnuPG version 2.0.30.
Can someone explain why the following will not work on my Windows machine:
echo "passphrase"| gpg2 --batch --yes --always-trust --passphrase-fd 0 -es -r "Public key for encryption" "Path of file to encrypt"
To my knowledge, this should be piping the output of echo (my passphrase) as the input of --passphrase-fd 0 (0 operating on STDIN handle of course). I can't seem to get this to work, and wasn't sure if it was my code, or if it's just an issue running this on Windows.
Whenever I execute this command, I get
"no default secret key: Bad passphrase"
"sign+encrypt failed: Bad passphrase"
As a workaround, I was able to use redirection operater < and passed the filepath to my passphrase, still using the STDIN handle (0):
gpg2 --batch --yes --always-trust --passphrase-fd 0 -es -r "Public key for encryption" "Path of file to encrypt" < "Filepath to passphrase"
I realize it's bad practice to store a passphrase in a local file, and may consider removing the signature altogether, but for my own sake, I want to better understand why this won't work using piping (on Windows).
Thanks!
I am extracting data to .psv files through a script. These .psv files have to be encrypted and SFTPed to antoher server location. But the extracted psv files are not getting encrypted. It is throwing the following error:
gpg: Invalid option "--trust-model"
I am using the following command
gpg -r 'abc#def.com' --encrypt --trust-model always $File_Name
Please help.
Thanks.
I've never seen the --trust-model always option myself, but I think you need to specify the file name last (or at least following the --encrypt option). So, try this:
gpg -r 'abc#def.com' --trust-model always --encrypt $File_Name
I have seen, but never personally used the --always-trust option, so here's another thing you can try:
gpg -r 'abc#def.com' --always-trust --encrypt $File_Name
I always add "trust" to every key I add to my ring so I'm not familiar with either of these options.
If I run gpg to sign and encrypt a file from the command line, it works. I have an application that tries the same and I get the following error. The application has worked signing and encrypting before, so I do not think that it is a permission issue. Any ideas?

Why is your program including the paths to the public and secret keyrings? GPG should find them in the home directory, if you're using a different location for those files then you either need to specify the new home directory (with the --homedir flag) or prepend the two keyring files with the relevant flags (--keyring and --secret-keyring).
As it is, that command appears to be trying to encrypt your public and secret keyrings to the "JPMC_ECS_PROD_2015" recipient. If "JPMC_ECS_PROD_2015" is not a group name (specified in the gpg.conf file) or specified elsewhere in the code for your program, then that will generate errors relating to an invalid recipient (or recipient format).
i am struggling with a gpg problem for a few days and cant figure out a solution by my own. i would be glad if you could help me out with the following issue:
i need to decrypt a gpg file in php. for that, i am using the following command:
cat passphrase.txt | /usr/local/bin/gpg --decrypt --passphrase-fd 0 stammdaten.txt.gpg>stammdaten.txt
the passphrase.txt contains the password for decryption
stammdaten.txt.gpg is the encrypted file
the decrypted data will be written in stammdaten.txt
when i run this command in php:
shell_exec=("cat passphrase.txt | /usr/local/bin/gpg --decrypt --passphrase-fd 0 stammdaten.txt.gpg>stammdaten.txt")
i get a zero-byte output file (stammdaten.txt) with owner=ftpadmin and group=psacln
but when i execute the same command via ssh terminal (as root), the data will be decrypted and written correctly with file owner=root and group=root.
i think, that this is a permission problem. how can i use that command in php correctly? i also tried to chown and chgrp with the ftprightson the decrypted file, but nothing seems to help.
every answer is highly appreciated. thanks!
finally i got it to work:
first of all, i changed the gpg command for decryption with echoing the passphrase into stdin:
$passphrase = utf8_decode('mypassphrase');
$encrypted = 'fullsystempathtogpgfile.gpg';
"echo '$passphrase' | /usr/local/bin/gpg -v -v --batch --passphrase-fd 0 --no-default-keyring $encrypted";
before executing with shell_exec i needed to change the homedir of gpg:
before it was set with:
putenv("GNUPGHOME=/var/www/.gnupg");
but obviously the php user (in my case "ftpadmin", found out with "whoami") has no permission to access that directory, so i copied the .gpg folder into my new created php user folder: /home/ftpadmin (with 777 perms) and changed the GNUPGHOME:
putenv("GNUPGHOME=/home/ftpadmin/.gnupg");
now i am able to decrypt the gpg files with php. maybe you could find some help for your similar issue. thanks again for every answer.
You can try to use
cat passphrase.txt | /usr/local/bin/gpg --output stammdaten.txt --decrypt --passphrase-fd 0 stammdaten.txt.gpg
instead.
Another thing you can try is to run this command in the shell as ftpadmin in the directory where your stammdaten.txt file is to make sure it is not a file permission problem.
su ftpadmin
cat passphrase.txt | /usr/local/bin/gpg --output stammdaten.txt --decrypt --passphrase-fd 0 stammdaten.txt.gpg
