” Skype does not store password directly. Instead it stores the encrypted hash of the password in the '
config.xml' located in Skype's user profile directory. Typical user profile directory for Skype will be as follows,
[Windows XP]C:Documents and Settings<user_name>Application DataSkype<account_name>
[Windows Vista & Windows 7]
C:Users<username>AppDataRoamingSkype<account_name>
This config.xml contains <Credentials2> tag which contains encrypted hash of the password. As per the research paper 'Vanilla Skype' written by Fabrice Desclaux and Kostya Kortchinsky, Skype uses the MD5 hash of string "usernamenskypernpassword" for authentication. If user has set the 'Remember password' option then this MD5 hash is encrypted using AES-256 & SHA-1 algorithms and finally saved into the 'Config.xml' file.
Since the HASH of the password is saved, it is not possible to directly get the password. Instead one has to use dictionary or brute force approach to find out the right password from the hash. This approach may take days or months together based on the length & complexity of the password.
You can use 'SkypePassword' from Lastbit to recover stored Skype password.

Нямам си на идея дали наистина паролата е в тоя файл, който е описан по-горе. Инфото го намерих от тук (ето и PDF-че, да не зачезне): 
Password_Secrets_of_Popular.pdf
Но, ако наистина е така, както е описано, тогава само brute-force атака или неща ала рейнбоу-таблици може да излекува забравена парола. А това си иска време
