This function is used to explicitly initialize a new session. Currently this function does nothing useful. But in future it may contain some code for initialization of the new session. We recommend you to use this function before you using any other XP_CRYPT functions.

Return Code Values

0 - success, or Error code if failed.

Permissions

Execute permissions default to the public role.

Example

-- Initialize session
exec xp_crypt_init_session
-- Set timeout to 1 minute
exec xp_crypt_set_option 'timeout','1' 
exec xp_crypt_set_option 'use_crlf','no' 
....
-- Encrypt string and get the result without new line feeds 
exec xp_rsa_priv_dec @CryptedText, '<privatekey.pem', @name OUTPUT, @dateofbirth OUTPUT , @department OUTPUT, 'PassForThePrivateKey'
-- Close session
exec xp_crypt_close_session
