.SH "DESCRIPTION"

\fB(ALPHA)\fR Creates a digital signature of the input file using the provided
asymmetric\-signing key version and saves the base64 encoded signature.

The required flag \f5signature\-file\fR indicates the path to store signature.

By default, the command performs integrity verification on data sent to and
received from Cloud KMS. Use \f5\-\-skip\-integrity\-verification\fR to disable
integrity verification.



.SH "EXAMPLES"

The following command will read the file '/tmp/my/file.to.sign', digest it with
the digest algorithm 'sha256' and sign it using the asymmetric CryptoKey
\f5dont\-panic\fR Version 3, and save the signature in base64 format to
\'/tmp/my/signature'.
