About the index files

The
ICE Cloud Console
uses the MD5 message-digest algorithm. This algorithm is a one-way hash function that takes as input a message of arbitrary length and produces as output a 128-bit message-digest or "fingerprint" of the input.
  • For exact file matches: If the message input is a file that the service cannot extract the contents from, such as an image file, small file, or unsupported file type, the service creates a cryptographic hash based on the binary signature of the file.
  • For partial content matches: the
    ICE Cloud Console
    extracts the contents from the documents. The service creates hashes for discrete sections of content or text passages of these documents. The service uses a selection method to store hashed sections of partial content so that not all extractable text is indexed. The hash function ensures that the index does not contain actual document content.
