Who will answer your question at midnight?

Let me briefly say my opinion:

First of all, your question is a fake question, and the question itself has a problem. Digital envelopes and digital signatures have different uses. How do you compare their advantages and disadvantages?

Secondly, I simply tell you their similarities and differences, hoping to help you:

Different uses: digital envelopes are used to convey confidential information, while digital signatures are used to ensure integrity and prevent denial.

Different sizes: because the digital envelope has to transmit data, its size is directly related to the amount of data, which may be several k or several g; Digital signature is generally less than 2K, because digital signature generally only encrypts the hash of data.

The main similarity is that asymmetric and symmetric key algorithms are used for encryption.
