Note: Chilkat began support for Ed25519 keys in version 9.5.0.83

CREATE PROCEDURE ChilkatSample
AS
BEGIN
    DECLARE @hr int
    -- This example assumes the Chilkat API to have been previously unlocked.
    -- See Global Unlock Sample for sample code.

    -- A private key, regardless of type or format (RSA, EC, DSA, Ed25519) can be loaded by
    -- calling LoadAnyFormat or LoadAnyFormatFile.

    -- Likewise, a public key, regardless of type or format can be loaded by calling
    -- LoadFromFile or LoadBd.

    -- For example:
    DECLARE @privKey int
    -- Use "Chilkat_9_5_0.PrivateKey" for versions of Chilkat < 10.0.0
    EXEC @hr = sp_OACreate 'Chilkat.PrivateKey', @privKey OUT
    IF @hr <> 0
    BEGIN
        PRINT 'Failed to create ActiveX component'
        RETURN
    END

    -- Pass an empty password if not needed.
    DECLARE @password nvarchar(4000)
    SELECT @password = ''
    DECLARE @success int
    EXEC sp_OAMethod @privKey, 'LoadAnyFormatFile', @success OUT, 'qa_data/eddsa/ed25519.pem', @password

    -- For example, an encrypted PKCS8 key of any type (Ed25519, RSA, EC, etc.)
    SELECT @password = 'secret'
    EXEC sp_OAMethod @privKey, 'LoadAnyFormatFile', @success OUT, 'qa_data/rsa/pkcs8.key', @password

    -- The same for public keys..
    -- (public keys never have nor need passwords)
    DECLARE @pubKey int
    -- Use "Chilkat_9_5_0.PublicKey" for versions of Chilkat < 10.0.0
    EXEC @hr = sp_OACreate 'Chilkat.PublicKey', @pubKey OUT

    EXEC sp_OAMethod @pubKey, 'LoadFromFile', @success OUT, 'qa_data/pubkeys/pubkey_pkcs1.der'

    EXEC @hr = sp_OADestroy @privKey
    EXEC @hr = sp_OADestroy @pubKey
