Encrypting password for email

[msalguer]

I read the configuration parameters from an .ini file. I do a reading, and I concatenating the parameters.
¿Why I do not get the same result? I attach the source code.
Continuous testing with unencrypted password. The values of the other parameters are the same as those listed above. This code does not work me. Appears error: Incorrect username or password:

ARRAY(str) var_name.create(17)
ARRAY(str) var_result.create(17)

var_name[0]="smtp_server"
var_name[1]="smtp_port"
