Steghide is a free open-source steganography program that allows users to hide data in different types of media files. It can be used to hide sensitive information in image and audio files, such as text, files, and even other image or audio files. Steghide uses a combination of cryptography and steganography to ensure that data is securely embedded. Steghide is a command line application, but there is also a GUI version available. It supports many different types of files, including JPEG, BMP, WAV, and AU. Steghide also supports encryption, allowing users to add an extra layer of security to the data they are hiding. It can also be used to verify the integrity of a file, by using a cryptographic hash function.
The discontinued official website cannot be accessed, but the download is still available on the download sites.
