simple class for serializable and secure credential holder

Simple Serializable Credential Holder

This is a simple class for handling credentials. It is serializable for data transfer and is able to securely hold credentials in its constructed form.

Usage

To get a serialized credential holder, start by picking a passphrase (that you must remember or keep track of) for usage as an encryption key. Then, create an instance of the CredentialHolder object using the credential you want to encrypt and the passphrase and you can serialize it and use the string to store or communicate the credentials.

from credential_holder import CredentialHolder, CredentialHolderSerializer


credential_holder = CredentialHolder("passphrase", "password")
serialized_credential_holder = CredentialHolderSerializer.serialize_credential_holder(credential_holder)

This creates something along the lines of

serialized_credential_holder = 'aG9sZGVyLl' + 'GQzXHInKQ==' # shortened representation of a large base64 string

This value can be then transferred and used elsewhere as follows

from credential_holder import  CredentialHolderSerializer

serialized_credential_holder = "same_as_above"

credential_holder = CredentialHolderSerializer.deserialize_credential_holder(serialized_credential_holder)

credential_holder.get_credential("passphrase")

Using the wrong passphrase will cause an Exception - you will not be able to decrypt a Credential Holder or serialized string unless you have the same passphrase that was used to create it.
