CryptoLibrary is a library for secure password handling. project page
For more information about Robot Framework, see http://robotframework.org.
If you already have Python >= 3.6 with pip installed, you can simply run:
pip install --upgrade robotframework-crypto
or if you have Python 2 and 3 installed in parallel you may use
pip3 install --upgrade robotframework-crypto
If you have Python 2 ... i am very sorry! Please update!
CryptoLibrary uses asymmetric crypto with elliptic curve cryptography to store confidential data securely.
With the command CryptoLibrary in console/terminal you can generate a key pair (private and public key) for your test env. You will get the public key after generating.
This public key can now be used to encrypt every data you do not want to be public. Passwords, personal data, etc.
You can use the commandCryptoClient on you computer where you want to encrypt data.
Encrypted Data will look like this:
crypt:tIdr5s65+ggfJZl46pJgljioCUePUdZLozgiwquznw+xSlmzT3dcvfrTL9wIdRwmNOJuONT7FBW5
This encrypted data can now be decrypted with CryptoLibrary within Robot Framework.
CryptoLibrary need the private_key_store.json for this. This is what is generated as key pair. Private key can be imported in test env with python -m CryptoLibrary .
All Data that is decrypted by CryptoLibrary is replaced in the log by *** This works always and can not be disabled. No need to use special keywords for this.
in this case the decryption password for the private key. It can also be saved on test env persistently as a hash.
The parameter variable_decryption in the Library call, if set to true it will automatically decode ALL passwords defined in the variables section and then "Get Decrypted Text" isn't needed.
| password: | Password for private key can be given as argument. This should be stored as secret! Use environment variables instead of hard coding it here. |
| variable_decryption: | If set to True all variables that are available on Test Suite or on Test Case start, that contain a encrypted text, will be decrypted automatically. |
| key_path: | A path that defines where the key pair is stored physically. Path needs to be an absolute path or relative to cryptoutility.py. |
This Command Line tool has to be used to create a key pair. It can also show the public key and encrypt or decrypt data.
python -m CryptoLibrary:
? What do you want to do? (Use arrow keys)

Decrypt
Open config ---> ? What do you want to do? (Use arrow keys)
Quit Configure key pair -----------------------------------------------------------------------------------------> ? What do you want to do? (Use arrow keys)

Quit Your password is: YourPassword crypt:TheEncryptedPassword=To start using the CryptoLibrary, start python -m CryptoLibrary and choose Open config -> Configure key pair-> Generate key pair.
This generates the private and public keys in the private_key.json and public_key.key files. The private_key.json is needed to decrypt the values on your test server and has to be copied manually or added through the CLI interface. See Set key pair from... above.
Next you can encrypt the values needed on your test server, looking something like crypt:nkpEPOVKfOko3t04XxOupA+F/ANTEuR9aQuPaPeMBGBQenwYf6UNESEl9MWRKGuj60ZWd10=
There are two options to decrypt your values in the robot file. When CryptoLibrary is loaded with variable_decryption=True, ALL variables defined in that section, will automatically get decrypted. When the option is turned off (the default) the keyword Get Decrypted Text explicitly decrypts specific values.
This CryptoClient command line tool is the tool for all test designers that want to encrypt data. I can only import and show the public key and encrypt data.
python -m CryptoClient:
? What do you want to do? (Use arrow keys)
Encrypt ---------------------------------------------------------------------------------------> ? Enter the password to encrypt YourPassword
Open config -----> ? What do you want to do? (Use arrow keys) Encrypted password: (use inlc. "crypt:")
Quit Set public key from string ---> ? Input public_key as Base64: ThePublicKey
Get public key from string ---> Public Key: ThePublicKey crypt:TheEncryptedPassword
Delete public key ---> ? Do you really want to delete public key?
BackCryptoLibrary.Plugin is a SeleniumLibrary Plugin. When taken into usage, the Input Password Keyword can now handle decrypted cipher texts as well.
Example:
It may happen that keywords changes. i try not to do, but it can happen in major releases. Feel free to make a pull Request to improve docs or write some tests for it.
