What is an opaque pointer type?

In computer programming, an opaque pointer is a special case of an opaque data type, a data type declared to be a pointer to a record or data structure of some unspecified type. This benefits the programmer as well since a simple interface can be created, and most details can be hidden in another file.

What is an opaque object C++?

from Wikipedia. In computer science, an opaque data type is a data type that is incompletely defined in an interface, so that its values can only be manipulated by calling subroutines that have access to the missing information.

What is an opaque function?

As you mention in the question, an opaque function call is a call to a function that the compiler has no prior information about. This implies that the compiler can make no assumptions about the side effects of this call except what is guaranteed by the language definition.

What is an opaque struct in C?

Some languages, such as C, allow the declaration of opaque records (structs), whose size and fields are hidden from the client. The only thing that the client can do with an object of such a type is to take its memory address, to produce an opaque pointer. This is usually the case for opaque pointers.

What is opaque pointer in Swift?

Overview. Opaque pointers are used to represent C pointers to types that cannot be represented in Swift, such as incomplete struct types.

What is an opaque string?

By “opaque” they mean that the inner structure exists, but is unknown. So the program is expected to treat the string as a whole – store it, transmit it, but not try to interpret.

What is opaque object in C?

Opaque types are, in part, a way to make C more object-oriented. They allow encapsulation, so that the internal details of a type can change–or be implemented differently in different platforms/situations–without the code that uses it having to change.

What is opaque key?

An opaque key is a type of key that allows you to perform cryptographic operations such as encryption, decryption, signing, and verification, but does not allow access to the key itself. Typically an opaque key is loaded from a hardware security module (HSM). plaintext. User-readable data you care about.

What are opaque strings?

What is opaque password?

Enter OPAQUE: a Password-Authenticated Key Exchange (PAKE) protocol that simultaneously proves knowledge of a password and derives a secret key.

Should I encrypt password over https?

Quick Answer: It is a standard practice to send “plain text” passwords over HTTPS via POST method. As we all know the communication between client-server is encrypted as per TLS, so HTTPS secures the password.
