When recreating a procedure for signature, all the statements in the original batch must match recreation batch. If a module contains an EXECUTE AS clause, the security ID (SID) of the principal is also included as a part of the signing process. The signature of a module is dropped when the module is changed. This includes leading carriage returns and line feeds.Ī module can be signed and countersigned by any number of certificates and asymmetric keys. Every character in the module is included in the signature calculation. The module being signed or countersigned and the certificate or asymmetric key used to sign it must already exist. Is the name of an asymmetric key with which to sign or counter-sign the stored procedure, function, assembly, or trigger. signed_blob is the blob itself in hexadecimal format. When you use this clause, only the module, signature, and public key are required to add the signed binary large object to a database. This clause is useful if you want to ship a module without shipping the private key. Specifies the signed, binary large object (BLOB) of the module. This clause is only required if the private key isn't protected by the database master key.
