Name
sq-certify — Certifies a User ID for a Certificate
Using a certification a keyholder may vouch for the fact that another certificate legitimately belongs to a user id. In the context of emails this means that the same entity controls the key and the email address. These kind of certifications form the basis for the Web Of Trust.
This command emits the certificate with the new certification. The updated certificate has to be distributed, preferably by sending it to the certificate holder for attestation. See also "sq key attest-certification".
Synopsis
sq certify [Flags] [Options] <CERTIFIER-KEY> <CERTIFICATE> <USERID>
Flags
- -h, --help
Prints help information
- -B, --binary
Emits binary data
- -l, --local
Makes the certification a local certification. Normally, local certifications are not exported.
- --non-revocable
Marks the certification as being non-revocable. That is, you cannot later revoke this certification. This should normally only be used with an expiration.
Options
- -o, --output FILE
Writes to FILE or stdout if omitted
- -d, --depth TRUST_DEPTH
Sets the trust depth (sometimes referred to as the trust level). 0 means a normal certification of <CERTIFICATE, USERID>. 1 means CERTIFICATE is also a trusted introducer, 2 means CERTIFICATE is a meta-trusted introducer, etc. The default is 0.
- -a, --amount TRUST_AMOUNT
Sets the amount of trust. Values between 1 and 120 are meaningful. 120 means fully trusted. Values less than 120 indicate the degree of trust. 60 is usually used for partially trusted. The default is 120.
- -r, --regex REGEX
Adds a regular expression to constrain what a trusted introducer can certify. The regular expression must match the certified User ID in all intermediate introducers, and the certified certificate. Multiple regular expressions may be specified. In that case, at least one must match.
- --notation NAME
Adds a notation to the certification. A user-defined notation's name must be of the form "name@a.domain.you.control.org". If the notation's name starts with a !, then the notation is marked as being critical. If a consumer of a signature doesn't understand a critical notation, then it will ignore the signature. The notation is marked as being human readable.
- --expires TIME
Makes the certification expire at TIME (as ISO 8601). Use "never" to create certifications that do not expire.
- --expires-in DURATION
Makes the certification expire after DURATION. Either "N[ymwd]", for N years, months, weeks, or days, or "never". [default: 5y]
Args
- CERTIFIER-KEY
Creates the certificate using CERTIFIER-KEY.
- CERTIFICATE
Certifies CERTIFICATE.
- USERID
Certifies USERID for CERTIFICATE.
Examples
- # Juliet certifies that Romeo controls romeo.pgp and romeo@example.org
$ sq certify juliet.pgp romeo.pgp "<romeo@example.org>"
