Extract text from nautical permit files (ENP)
To convert ENP permits to another format, you need ADMIRALTY e-Reader or other Encoded software.
To convert other file formats to the "Security Permit & GIS Project" file type, you need software like ADMIRALTY e-Reader or a similar tool.
The .ENP file extension represents several distinctly different formats, most notably acting as an Electronic Nautical Publication Permit, an ENVI Project File, or an Encrypted File Container.
As an Electronic Nautical Publication (ENP) permit, this file is generated by the UK Hydrographic Office (UKHO) to license and decrypt digital maritime charts within the ADMIRALTY e-Reader software. These files are pure digital signatures and cannot be converted into standard documents like PDF or DOCX. Attempting to do so breaks the required cryptographic chain for maritime compliance.
Alternatively, an .ENP file is heavily used as an ENVI Project File by L3Harris Geospatial Solutions. Here, it stores raster metadata and complex remote sensing workflows. Finally, .ENP files are frequently created as secure archives by encryption software such as Entrust or AxCrypt. In these cases, the file is a proprietary, locked vault requiring a specific user passphrase.
These varied, highly technical formats make standard file conversion nearly impossible. Online converters fail because they cannot decrypt the security payloads of an Entrust archive, parse the specialized coordinate data of an ENVI project, or read proprietary UKHO maritime permits. Users are heavily restricted to using the original software to interact with the file. Our analyzer will inspect the binary signature to determine exactly which type of .ENP file you possess. If our analysis detects an underlying text structure or supported embedded data, partial viewing or extraction may still be achievable.
Convert.Guru analyzes your ENP file, detects the exact format, and lets you read the text inside.
Users also converted ENB, STAT, VTK and EDR files.
If you want to convert ENP file to TMP, TEMP, CACHE, LOG, BAK, OLD, NEW, PART, DOWNLOAD, CRDOWNLOAD, LOCK or PID, you can use ADMIRALTY e-Reader or similar software from the "Encrypted Data & Project Storage" category. In the File menu, look for Save As… or Export….
To convert DEVICE, CACHE, SOCK, SYMLINK, PID, MOUNT, FIFO, LOG, PIPE, TMP, JUNCTION or TEMP files to ENP, try ADMIRALTY e-Reader or another comparable tool in the "Encrypted Data & Project Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ENP converter.
