What is NOT a method of encryption supported by CyberArk?

In the context of CyberArk's encryption methods, the selection of SHA-512 as the option that is not a supported method is correct because SHA-512 is not an encryption algorithm; it is a cryptographic hash function. Hash functions, including SHA-512, are designed to take input data and produce a fixed-size string of characters, which serves as a unique identifier for that data, but they do not enable reversible data encryption. This means that while SHA-512 can validate data integrity by producing a consistent hash for unchanged data, it does not provide confidentiality through encryption.

On the other hand, AES-256, RSA-2048, and 3DES are all recognized encryption algorithms that provide mechanisms to securely encrypt and decrypt data. AES-256 is widely used due to its robust security and efficiency. RSA-2048 is a widely used asymmetric encryption standard suitable for secure data transmission, while 3DES, although considered less secure than AES, is still categorized as an encryption method available in various systems, including CyberArk.

Thus, knowing the distinction between encryption algorithms and hashing algorithms clarifies why SHA-512 does not fit the criteria of being a supported encryption method within CyberArk.
