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

Create a passphrase that is used as an encryption key and create an instance of the object using the credential you want to encrypt and the passphrase. Then you can serialize it and use the string to store or communicate the credentials, e.g.

from credential_holder.holder import CredentialHolder
from credential_holder.serializer import  CredentialHolderSerializer


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

This creates something along the lines of

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

This value can be then transferred and used elsewhere as follows

from credential_holder.serializer import  CredentialHolderSerializer

serialized_credential = "same_as_above"

serialized_credential_holder = CredentialHolderSerializer.deserialize_credential_holder(serialized_credential)

serialized_credential_holder.get_credential("passphrase")

Using the wrong passphrase or supplying an invalid serialized credential holder will raise an exception
