Generate a digital signature of an existing message digest:

When verifying the signature, the digest will not be hashed again:

Create signatures of several messages:

Verify their signatures:

Generate an elliptic curve–based key pair:

Generate a digital signature using your private key:

Verify a digital signature using your public key:

Verify the signature in a self-signed certificate. Import the certificate:

In a self-signed certificate, the issuer and the subject of the certificate are the same entity:

Verify if the signature is valid for the key and the information on the certificate:

Generate a digital signature compatible with Bitcoin network requirements:

Verify the signature:

Generate a digital signature compatible with Ethereum network requirements:

Verify the signature:

Use raw ByteArray data directly:

Use "HashingMethod"->None if you have an already hashed digest:

When verifying the signature, the digest will not be hashed again:

Generate a pair of elliptic curve keys:

Import the contents of the file you wish to sign:

Create a signature for the imported bytes of the file:

Equivalently, this can be done using GenerateFileSignature on the file directly:

Both signatures are verifiable:
