要約

関数: string llSignRSA( string private_key, string msg, string algorithm );

that is the "Wikipedia logo"Base64-encoded "Wikipedia logo"RSA signature of msg when using hash algorithm algorithm and secret key private_key. Can be paired with llVerifyRSA to pass verifiable messages.を string で返します。

• string private_key
• string msg
• string algorithm

This function supports sha1, sha224, sha256, sha384, sha512 for algorithm.

サンプル

// Generate an signature, then immediately verify if it is valid.
