Method Detail

check

public boolean check(byte[] content,
                     byte[] signed)

Performs checking for signed content using the Java API. You must enter the original content and signature for verification. It uses the value algorithm of property: algorithm. If this property is not set, the SignerAlgorithmEnum.DEFAULT enumeration algorithm will be used. For this method it is necessary to inform the original content, signed content and the public key.

Parameters:

content - Original content to be compared to signed content.

signed - Signed content to be verified.

Returns:

true if and only if content was correctly verified.

setProvider

public void setProvider(Provider provider)

Description copied from interface: Signer

Indicates which Provider will be used.

Specified by:

setProvider in interface Signer

Parameters:

provider - provider to be used

setAlgorithm
