As of 2025, the LocalTgzve format is being phased out in favor of encrypted tar.zst with age encryption (age tool). However, millions of legacy links remain active in on-premise storage systems.
Use a hex editor to open the .localtgzve file. Look for the magic bytes: 0x4C 0x54 0x47 0x56 (LTGV in ASCII). Following this is a 4-byte integer representing the encrypted payload offset.
Command (Python):
with open("target.localtgzve", "rb") as f:
header = f.read(16)
if header[:4] == b'LTGV':
offset = int.from_bytes(header[12:16], 'little')
print(f"Payload starts at byte offset")
That is a URI pointer. Decrypt the target of the link, not the string itself. Use curl or wget to fetch the encrypted file from the local server path:
curl "localtgzve://192.168.1.100/backup" --output fetched.localtgzve
Then apply the decryption steps.
We will assume you are on a Linux or macOS system (or WSL on Windows) with terminal access. The process involves two phases: decrypting the link to reveal a standard .tgz archive, then extracting that archive.
The majority of localtgzve implementations use AES-256-CBC via OpenSSL. If the header contains Salted__, run: decrypt localtgzve link
# Assuming you have the passphrase: "MySecretKey2024"
openssl enc -aes-256-cbc -d -in file.localtgzve -out decrypted_archive.tgz -pass pass:MySecretKey2024
If the passphrase is in a file:
openssl enc -aes-256-cbc -d -in file.localtgzve -out decrypted_archive.tgz -pass file:./key.txt
For the localtgzve:// link string itself: Sometimes the link is Base64-encoded after encryption. Decode first: As of 2025, the LocalTgzve format is being
# If the link looks like "localtgzve://U2FsdGVkX1..."
echo "U2FsdGVkX1..." | base64 --decode | openssl enc -aes-256-cbc -d -pass pass:yourkey
Decrypting a .local.tgz file involves mounting it as a VeraCrypt volume. If the .local.tgz file is indeed a VeraCrypt container or if you're dealing with VeraCrypt configuration/settings, here are the general steps. Please ensure you have a backup of your data before proceeding.
Solution: Padding mismatch. Add -nopad to OpenSSL or ensure you are using the correct cipher mode (CBC vs ECB). That is a URI pointer
