I have not tried it but you can do
class EncryptedField(Field):
def __init__(self,*a,**b):
self.password = b['password']
del b['password']
Field.__init__(self,*a,**b)
def store(self,file, filename=None, path=None):
newfile = encrypt(file,self.password)
return Field.store(self,file,filename,path)
def retrieve(self, name, path=None):
(filename, file) = Field.retrieve(self,name,path)
newfile = decrypt(file,self.password)
return (filename, newfile)
the use
db.define_table('person',Field('name'),EncryptedField('secret','upload',password='too
many secrets!'))
