A Python toolkit for gocryptfs v2 encrypted filesystems, inspired by pycryptomator.
Provides full programmatic and shell-based access to a gocryptfs vault without needing the FUSE driver installed.
Requirements
- Python ≥ 3.10
pycryptodomeorpycryptodomeX
pip install pycryptodome
Supported feature flags

|---|---|
| HKDF + GCMIV128 | ✅ required baseline |
| EMENames + DirIV | ✅ per-directory IV + EME wide-block name encryption (default) |
| Raw64 | ✅ unpadded base64 names |
| PlaintextNames | ✅ unencrypted names |
| AESSIV | ✅ AES-SIV content encryption |
| XChaCha20Poly1305 | ✅ XChaCha20 content encryption (gocryptfs ≥ 2.2) |
| LongNameMax | ✅ configurable long-name threshold |
| FIDO2 | ❌ not supported |
| Reverse mode | ❌ not supported |
| gocryptfs v1 (no HKDF) | ❌ not supported |
Interactive shell
python -m pygocryptfs /path/to/vault
# or with explicit password
python -m pygocryptfs --password mypassword /path/to/vault
The shell understands these commands:
| Command | Description |
|---|---|
ls [-b] [-r] [-s NSDE-!] [path ...] |
List virtual directory contents |
cd <dir> |
Change current virtual directory |
pwd |
Print current virtual directory |
cat <file> |
Decrypt a file to stdout |
decrypt [-f] [-m] [-F] <vsrc> ... <real_dest> |
Decrypt file(s)/dir(s) to the real FS |
encrypt [-f] [-m] [-F] <real_src> ... <vdest> |
Encrypt file(s)/dir(s) into the vault |
mkdir [-R] <dir> [...] |
Create virtual directory/ies |
mv <src> [src2 ...] <dest> |
Move / rename |
rm [-f] <path> [...] |
Remove file(s)/dir(s) (-f = force recursive) |
alias <vpath> [...] |
Show real pathname of a virtual path |
backup <zip> |
Backup all gocryptfs.diriv to a ZIP |
quit / exit |
Exit the shell |
Shell wildcards (*, ?) are supported for all commands.
ls sort specifiers
| Char | Meaning |
|---|---|
N |
by Name |
S |
by Size |
D |
by Date |
E |
by Extension |
- |
reverse subsequent key |
! |
toggle reverse |
Single-command mode
python -m pygocryptfs --password secret /vault ls /
python -m pygocryptfs --password secret /vault decrypt /secret.txt /tmp/out.txt
python -m pygocryptfs --password secret /vault encrypt /tmp/myfile.txt /
Initialise a new vault
python -m pygocryptfs --init --password mypassword /path/to/new/vault
Print / backup the master key
# Print in hex (default)
python -m pygocryptfs --password secret --print-key /vault
# Print in base64
python -m pygocryptfs --password secret --print-key b64 /vault
# Print in ASCII85
python -m pygocryptfs --password secret --print-key a85 /vault
Change the vault password
python -m pygocryptfs --password oldpass --change-password /vault
Programmatic API
from pygocryptfs import Vault, init_vault, backupDirIds
# Open an existing vault
v = Vault('/path/to/vault', password='secret')
# List root
v.ls(['/'])
# Decrypt a file
v.decryptFile('/documents/report.pdf', '/tmp/report.pdf', force=True)
# Encrypt a file
v.encryptFile('/tmp/photo.jpg', '/photos/photo.jpg')
# Walk the virtual filesystem
for root, dirs, files in v.walk('/'):
print(root, dirs, files)
# Create a directory
v.mkdir('/new_folder')
# Move / rename
v.mv('/old_name.txt', '/new_name.txt')
# Remove
v.remove('/unwanted.txt')
v.rmtree('/old_folder')
# Backup directory IVs
backupDirIds('/path/to/vault', '/tmp/diriv_backup.zip')
