Name
decrypt — Encrypt content in base64 encoding
Synopsis
varchar decrypt ( |
in base64_string_session any , |
in key_name varchar
); |
Description
Returns decrypted content as a string_session. The algorithm to encrypt depends of the key, so if the key is AES the AES will be used, if it is 3DES it is 3DES etc. The AES key can be created with xenc_key_AES_rand_create (key_name, 256). Alternatively 3DES key can be generated with xenc_key_3DES_rand_create ().
Parameters
base64_string_session
A base64 string content to be decrypted.
key_name
The key name keeping secret.
Return Types
On success the function will return decrypted content as a string_session.
