I need to create a Microsoft Access database, but have a need, in one of my tables, for a single field to be strongly encrypted.
Since AES requires both a key and an initialization vector, I've decided to solve this problem by requiring a password to access the database (as the key), and a field in the table to hold a SHA1 hash of the plaintext of the encrypted field.
Does anyone know where I can find VBA-compatible code to actually do the encryption?
