Secure file copy to Amazon Elastic Compute Cloud (Amazon EC2)

1. First connect to the instance using ssh command, make sure .pem (private key) is available in your ssh directory in ~/.ssh with permission chmod 400 <<my-key-pair.pem>>

> ssh -i my-key-pair.pem ec2-user@ec2-198-51-100-1.compute-1.amazonaws.com

2.  After successfully connected, Execute the following command

> scp -ir my-key-pair.pem <<Source path>> ec2-user@ec2-198-51-100-1.compute-1.amazonaws.com:<<destination path>>

resources :photos

Creates seven different routes in your application, all mapping to the Photos controller:

HTTP Verb	Path	Controller#Action	Used for
GET	/photos	photos#index	display a list of all photos
GET	/photos/new	photos#new	return an HTML form for creating a new photo
POST	/photos	photos#create	create a new photo
GET	/photos/:id	photos#show	display a specific photo
GET	/photos/:id/edit	photos#edit	return an HTML form for editing a photo
PATCH/PUT	/photos/:id	photos#update	update a specific photo
DELETE	/photos/:id	photos#destroy	delete a specific photo

gpg: public key decryption failed: Bad passphrase

When I  try to decrypt a file using GPG, for which I use "Starksoft.Cryptography.OpenPGP". I got the following error

Starksoft.Cryptography.OpenPGP.GnuPGException: An error occurred while trying to execute command --list-secret-keys.

But when I execute the command through command prompt ">gpg --list-secret-keys", it does list the keys. I could not get "Starksoft.Cryptography.OpenPGP" to work correctly.

Next I tried to get a solution by running the process directly using cmd.exe, which worked perfectly.

>echo Mypasspharse|gpg.exe --passphrase-fd 0 -o "C:\successtest.txt" --decrypt "C:\testfile.txt.gpg"

Note:

If Mypassphare contain a character ">" which will get interpreted as std out redirect in windows command prompt. So, passphase will not pass to the next command properly. So make sure you are not using  ">" in Passphase, if you are planning to use command prompt for gpg decryption
