Rust

rust-strings is available on crates.io and can be included in your Cargo enabled project like this:

[dependencies]
rust-strings = "0.6.0"

Usage

Python

import rust_strings

# Get all ascii strings from file with minimun length of string
rust_strings.strings(file_path="/bin/ls", min_length=3)
# [('ELF', 1),
#  ('/lib64/ld-linux-x86-64.so.2', 680),
#  ('GNU', 720),
#  ('.<O', 725),
#  ('GNU', 756),
# ...]

# You can also set buffer size when reading from file (default is 1mb)
rust_strings.strings(file_path="/bin/ls", min_length=5, buffer_size=1024)

# You can set encoding if you need (default is 'ascii', options are 'utf-16le', 'utf-16be')
rust_strings.strings(file_path=r"C:\Windows\notepad.exe", min_length=5, encodings=["utf-16le"])

# You can set multiple encoding
rust_strings.strings(file_path=r"C:\Windows\notepad.exe", min_length=5, encodings=["ascii", "utf-16le"])

# You can also pass bytes instead of file_path
rust_strings.strings(bytes=b"test\x00\x00", min_length=4, encodings=["ascii"])
# [("test", 0)]

# You can also dump to json file
rust_strings.dump_strings("strings.json", bytes=b"test\x00\x00", min_length=4, encodings=["ascii"])
# `strings.json` content:
# [["test", 0]]
