Tie::EncryptedHash augments Perl hash semantics to build secure, encrypting
|
|
containers of data. Tie::EncryptedHash introduces special hash fields that are
|
|
coupled with encrypt/decrypt routines to encrypt assignments at STORE() and
|
|
decrypt retrievals at FETCH(). By design, encrypting fields are associated with
|
|
keys that begin in single underscore. The remaining keyspace is used for
|
|
accessing normal hash fields, which are retained without modification.
|
|
|
|
While the password is set, a Tie::EncryptedHash behaves exactly like a standard
|
|
Perl hash. This is its transparent mode of access. Encrypting and normal fields
|
|
are identical in this mode. When password is deleted, encrypting fields are
|
|
accessible only as ciphertext. This is Tie::EncryptedHash's opaque mode of
|
|
access, optimized for serialization.
