Get-SodiumPublicKey

SYNOPSIS

Derives a Curve25519 public key from a provided private key using the Sodium cryptographic library.

SYNTAX

Base64 (Default)

Get-SodiumPublicKey -PrivateKey <string> [<CommonParameters>]

AsByteArray

Get-SodiumPublicKey -PrivateKey <string> -AsByteArray [<CommonParameters>]

ALIASES

This cmdlet has the following aliases, {{Insert list of aliases}}

DESCRIPTION

Takes a base64-encoded Curve25519 private key and returns the corresponding base64-encoded public key. This is accomplished using the Libsodium crypto_scalarmult_base function provided by the PSModule.Sodium .NET wrapper. The function ensures compatibility with cryptographic operations requiring key exchange mechanisms.

EXAMPLES

EXAMPLE 1

Get-SodiumPublicKey -PrivateKey 'ci5/7eZ0IbGXtqQMaNvxhJ2d9qwFxA8Kjx+vivSTXqU='

Output:

WQakMx2mIAQMwLqiZteHUTwmMP6mUdK2FL0WEybWgB8=

Derives and returns the public key corresponding to the given base64-encoded private key.
