| The password is hardcoded. It is split into two parts in memory,
V2VsbCBkb25lISBUaGlzIGFwcGxpY2F0aW9uIHdhcyB3cml0dGVuIGluIHB1cmUgQ and ywgYW5kIHlvdSBjcmFja2VkIGl0Lg==. Once you combine them you get the actual password, which is V2VsbCBkb25lISBUaGlzIGFwcGxpY2F0aW9uIHdhcyB3cml0dGVuIGluIHB1cmUgQywgYW5kIHlvdSBjcmFja2VkIGl0Lg==. It is a base64 string. "Well done! This application was written in pure C, and you cracked it." |
