Could you elaborate on the capabilities of assemblers and their potential integration with cryptographic extensions? I'm curious to understand if assemblers, as low-level programming languages, have the flexibility to leverage specialized crypto hardware instructions or extensions. Would this allow for optimized cryptographic operations, such as encryption, decryption, or hashing, at a hardware-level? Are there any limitations or challenges in implementing such extensions within assembler code, and how might this affect the overall security and performance of a cryptographic system?

Cryptocurrency instructions are typically not a part of the fundamental instruction set and thus require explicit specification for their utilization.

To incorporate cryptographic extensions into your code, you must inform the assembler of your intention.

One method to achieve this is by appending the directive ".arch armv8-a+crypto" to your assembler code.

This directive instructs the assembler to include the cryptographic extensions of the ARMv8-A architecture.

It's crucial to remember that the assembler is unaware of the specific extensions supported by your target machine unless you explicitly specify them.
