optional digest of message content ( Hash sign ) #929

Open blackkus opened 2 years ago

blackkus commented 2 years ago

Sometime you want to sign based on a Hash instead of a content (document). it means that you may not have the document, just the hash. Could it be possible to "digest" the content message only id "messageDigest" not provided :

Something like this :

if(attr.type === forge.pki.oids.messageDigest) {
    // use content message digest as value if not already set
    if(!attr.value) {
        attr.value = mds[signer.digestAlgorithm].digest();
    }
}
