You can also generate a public key for your SSH servers, using one of the two following commands, depending on your server: puttygen decrypted_key.key -O public-openssh -o decrypted_key.pub puttygen decrypted_key.key -O public -o decrypted_key. If you use the unix cli binary: puttygen decrypted_key.key -O private -o putty_key.ppk ssh-keygen -p -f decrypted_key.key Step 4: Convert the key to PPK When a password prompt appears, you will need to leave it empty, by pressing the enter key twice. You will need to pre-convert the key to be ready to be converted by Puttygen. chmod 600 decrypted_key.key Step 3: Pre-converting the key without defining a password Without that, ssh-keygen will refuse to work on the file. To prevent security risks, apply appropriate permissions on the key file. In case of error, a message will describe an password or decryption issue. if you used Keybot, you will first need to decipher it: openssl rsa -in encrypted_key.pkey -out decrypted_key.key Setp 1: Deciphering the key (if pertinent) The environment variable OPENSSLCONF can be used to specify the location. Many commands use an external configuration file for some or all of their arguments and have a -config option to specify that file. As you can imagine, being able to encrypt and decrypt files with strong ciphers is a useful function. The conversion requires OpenSSL, OpenSSH, and Putty. The openssl program provides a rich variety of commands, each of which often has a wealth of options and arguments. With OpenSSL, it is very easy to encode and decode Base64 data: openssl enc -base64 -in myfile -out myfile.b64 openssl enc -d -base64 -in myfile.b64 -out crypt Symmetric Encryption/Decryption of Files. The -A option when used with large files doesn't work properly. Base64 decode a file then decrypt it using a password supplied in a file: openssl enc -aes-256-ctr -pbkdf2 -d -a -in file.aes256 -out file.txt \ -pass file: BUGS.You can convert a base64/pem key, used by OpenSSL, or OpenSSH, to the Putty PPK format. openssl enc -aes-256-ctr -pbkdf2 -a -in file.txt -out file.aes256.
