This class provides read-only access to a file's contents in Truxton.
From IOBase it implements:
- close()
- closed
- fileno()
- flush() - Does nothing
- isatty()
- readable()
- readline()
- readlines()
- seek()
- seekable()
- tell()
- truncate() - Does nothing
- writable() - Always returns False
- writelines() - Always returns IOError
From RawIOBase it implements:
The above methods will let you read from a file in Truxton as if it were any other file in Python. The following methods are also present to make tasks of adding items extracted from a file easier.
Sample
This will retrieve a file from Truxton, print the name and hash as stored in the database then calculate a hash on the contents and print that.
import truxton
import hashlib
def main():
t = truxton.create()
file = t.getfileid("5ec2a123-74d6-5da7-0653-4e6800000000")
print(file.hash + " is the hash in the database for " + file.name )
bytes = file.readall()
readable_hash = hashlib.md5(bytes).hexdigest()
print(readable_hash + " is the calculated hash of the contents")
if __name__ == "__main__":
main()
