Can I hash/encrypt or otherwise protect emails in my Django app from hackers?

Question

Hoping for a simple function I can use to store emails securely and retrieve easily when required to send emails.

Answer 1

Kind of a general question, but here are a few solutions I'm familiar with:

• use django-encrypted-fields, which has an EncryptedEmailField
• you can override the save method for encrypting the email yourself, then override the post_init signal for decryption. See example here (which is based on this)
• you can build your own encrypted email field, see django snippet here (uses pyCrypto)
• you can use django-extension's EncryptedCharField
• If none of the above seems good enough, try google-ing around by yourself. You're probably not the first to tackle this problem

good luck.
