Digital signatures use cryptographic algorithms to create a unique digital fingerprint for each document,
which is then securely attached to the invoice. This digital fingerprint, known as a hash, ensures that any
alterations to the invoice can be detected. Additionally, digital signatures include a certificate issued by
a trusted authority, confirming the identity of the signer and guaranteeing the authenticity of the signature.
