Method Crypto.RSA.PKCS1_5State()->jose_sign()

Method jose_sign

string(7bit)|zero jose_sign(string(8bit) message, mapping(string(7bit):string(7bit)|int)|void headers, .Hash|void h)

Description

Signs the message with a JOSE JWS RSASSA-PKCS-v1.5 signature using hash algorithm h.

Parameter message

Message to sign.

Parameter headers

JOSE headers to use. Typically a mapping with a single element "typ".

Parameter h

Hash algorithm to use. Currently defaults to SHA256.

Returns

Returns the signature on success, and 0 (zero) on failure (typically that the hash + salt combo is too large for the RSA modulo).
