Hello all!
Probably this is a simple question, but i don't understand the right way...
Suppose I have the following table:
class User(Base):
__tablename__ = 'user'
id = Column(Integer, primary_key=True)
text_value = Column("text_value", String(40), nullable=False)
date_value = Column(«date_value", Date, nullable=False)
My task is to *store data* in this table *encrypted*, but i can’t
understand how to properly write encrypted type class (based on
TypeDecorator) for *non-string* columns (for example dates). Can anyone
give me a little example for date objects like this one. (
http://www.sqlalchemy.org/trac/wiki/UsageRecipes/SymmetricEncryption). Or
with this sql-level bind/result
processing<http://docs.sqlalchemy.org/en/rel_0_9/core/types.html#applying-sql-level-bind-result-processing>
.
As I think I should "wrap" all my columns in EncryptedString and save all
types as strings (convert and encrypt in process_bind_param) in DB and then
decrypt them in process_result_value. Am i right? And the other question,
how then provide a *quick lookup* in table for example *for dates*?
If it’s the wrong way prompt me the right way. :)
*Thanks*!
