SignAsync(byte[], byte[], string, PdfSigningOptions, CancellationToken)

Signs a PDF with a PKCS#12 (PFX) bundle handled entirely by the managed engine: no operating-system key store is touched, which makes this the path for the browser (where platform crypto is unavailable) and for hosts that must not import keys. The bundle's extra certificates are embedded as the chain.

Parameters

input byte[]

The PDF to sign.

pkcs12File byte[]

The PKCS#12 bundle carrying the signer's certificate and private key.

pkcs12Password string

The bundle password. Empty for none.

options PdfSigningOptions

Signing options. Certificate is ignored; null applies the defaults.

cancellationToken CancellationToken

Cancels the operation.

Returns

Task<byte[]>

The signed PDF.
