int getSignatureSize(
	bool detached,
	HashAlgorithm hashAlgorithm
)

Function getSignatureSize ( 
	detached As Boolean,
	hashAlgorithm As HashAlgorithm
) As Integer

int getSignatureSize(
	bool detached, 
	HashAlgorithm hashAlgorithm
)

abstract getSignatureSize : 
        detached : bool * 
        hashAlgorithm : HashAlgorithm -> int

Parameters

detached: Type: SystemBoolean
true for a detached signature, false for an encapsulated signature.
hashAlgorithm: Type: de.softpro.signdocsdk.Enums.ESignPKCS7HashAlgorithm
Hash algorithm to be used for signature: #ha_md5, #ha_sha1, #ha_sha256, #ha_sha384, #ha_sha512, or #ha_ripemd160. This parameter also determines the size of encapsulated data (20 octets for ha_sha1) if @a aDetached is false.

Return Value

Type: Int32
A positive number which is an upper limit to the number of octets required for the ASN.1-encoded signature (excluding any RFC 3161 timestamp), zero on error.
