What is the difference between removing protection, editing permissions, printing permissions, and password retrieval functions?

2024-04-01 17:53:40

Restrict Opening: This mainly restricts access to documents. Specific conditions or permissions can be set, and only users who meet the conditions can open the document. This approach is typically used to control the visibility and accessibility of documents.
Encryption: The document content is encrypted using an encryption algorithm. Only users with the correct key or password can decrypt and view the document content.

The specific differences include:

Different purposes : Restricting access is mainly to control access, while encryption is mainly to protect the confidentiality of the document.
Different control methods: Restrict opening by setting conditions, encryption by key or password.
Different security : Encryption provides a higher level of security protection.

We provide two different services: removing permissions and cracking passwords. Choose the corresponding decryption method based on the encryption situation. Choosing the wrong one will cause the processing to fail! (as shown in the figure below)
