Crypt_GPG debugging process

: This article describes how to debug Crypt_GPG. For more information about PHP tutorials, see. Error output on the browser:

Error message output by the command line:

PHP Fatal error:  Uncaught PEAR_Exception: gpg-agent binary not found.If you are sure the gpg-agent is installed, please specify the location of the gpg-agent binary using the 'agent' driver option.in /usr/local/webdata/andy/fanli/citic/Crypt/GPGAbstract.php on line 278#0 /usr/local/webdata/andy/fanli/citic/Crypt/GPGAbstract.php(278): Crypt_GPG_Engine->__construct(Array)#1 /usr/local/webdata/andy/fanli/citic/gpg2.php(9): Crypt_GPGAbstract->__construct()#2 {main}  thrown in /usr/local/webdata/andy/fanli/citic/Crypt/GPG/Engine.php on line 601Fatal error: Uncaught PEAR_Exception: gpg-agent binary not found.If you are sure the gpg-agent is installed, please specify the location of the gpg-agent binary using the 'agent' driver option.in /usr/local/webdata/andy/fanli/citic/Crypt/GPGAbstract.php on line 278#0 /usr/local/webdata/andy/fanli/citic/Crypt/GPGAbstract.php(278): Crypt_GPG_Engine->__construct(Array)#1 /usr/local/webdata/andy/fanli/citic/gpg2.php(9): Crypt_GPGAbstract->__construct()#2 {main}  thrown in /usr/local/webdata/andy/fanli/citic/Crypt/GPG/Engine.php on line 601

The first error reported in browser is my analysis of permission issues, and the second is the true problem when running in shell. use brew to install gpg-agent as prompted.

Then I write the code as follows:

require_once'./Crypt/GPG.php';$gpg = new Crypt_GPG();$key = getKey();$gpg->addDecryptKey('zhangsanfeng','123456');$encrypted = file_get_contents('wait_for_decrpyt.txt.gpg');$data = $gpg->decrypt($encrypted);echo'
';var_dump($data);exit;
The decryption is successful !!!

The above describes the process of debugging Crypt_GPG, including the content, and hope to be helpful to friends who are interested in PHP tutorials.
