Cryptage des Fichiers Batch

J'essaie donc de crypter un mot de passe que mon entreprise utilise pour putty ssh. Le problème est que le PW utilise des caractères spéciaux et que le chiffrement / déchiffrement im utilisant ne fonctionne pas avec des caractères spéciaux depuis son extension retardée. À l'aide!
