About OTG Master
OTG Master is an Android utility that enables users to mount VeraCrypt-encrypted USB mass-storage devices directly on their mobile devices without requiring root access. By utilizing the Android USB Host API, the application reads raw sectors from connected USB drives, unlocks the VeraCrypt volume header using supported ciphers and key derivation methods, and exposes the decrypted filesystem through a standard Android DocumentsProvider. This allows other applications, such as file managers or galleries, to browse and interact with the unlocked volume seamlessly.

- Supports AES and Serpent ciphers with SHA-512 key derivation
- Reads and writes to FAT32 and exFAT filesystems
