Parameters

embeddedContent

ReadOnlySpan<Byte>

The content to sign and to include in the message.

destination

Span<Byte>

The buffer in which to write the encoded bytes.

signer

CoseSigner

The signer information used to sign embeddedContent.

bytesWritten

Int32

On success, receives the number of bytes written to destination.

associatedData

ReadOnlySpan<Byte>

The extra data associated with the signature, which must also be provided during verification.

Returns

Boolean

true if destination had sufficient length to receive the encoded message; otherwise, false.
