pub.security.keystore.pkcs7:sign

signerInfo	Document List Information about a single signer of the signed data object. Each signerInfo requires either a certificate chain and a private key or a key alias that references them.
	Key	Description
	keyStoreAlias	String Name of the keystore alias.
	keyAlias	String Alias of the private key.
	hashAlgorithm	String The algorithm to use when computing the digest of the provided data. Specify: MD5 (the default) SHA-1 SHA-256 SHA-384 SHA-512
data	byte[ ] Optional. Data in the form of a byte array to be digitally signed. Note: If both data and dataAsStream are provided, dataAsStream takes precedence.
dataAsStream	java.io.InputStream Optional. Data in the form of an input stream to be digitally signed. Note: If both data and dataAsStream are provided, dataAsStream takes precedence.
detachedSignature	String Flag specifying whether to generate a detached signature. A detached signature does not include the data that was signed. Set to: true to generate a detached signature. false to generate an implicit signature (one that includes the signed data). This is the default.

signature	byte[ ] Conditional. Signature generated in the form of a byte array from the supplied data. This is a DER-encoded representation of the SignedData object as specified in PKCS#7. signature is returned when the input parameter data is provided.
signatureAsStream	java.io.OutputStream Conditional. Signature generated in the form of an output stream from the supplied data. signatureAsStream is returned when the input parameter dataAsStream is provided.
