const pathTidyHelpSyn = `
Tidy up the backend by removing expired certificates, revocation information,

`

const pathTidyHelpDesc = `
This endpoint allows expired certificates and/or revocation information to be
removed from the backend, freeing up storage and shortening CRLs.

For safety, this function is a noop if called without parameters; cleanup from
normal certificate storage must be enabled with 'tidy_cert_store' and cleanup
from revocation information must be enabled with 'tidy_revocation_list'.

The 'safety_buffer' parameter is useful to ensure that clock skew amongst your
hosts cannot lead to a certificate being removed from the CRL while it is still
considered valid by other hosts (for instance, if their clocks are a few
minutes behind). The 'safety_buffer' parameter can be an integer number of
seconds or a string duration like "72h".

All certificates and/or revocation information currently stored in the backend
will be checked when this endpoint is hit. The expiration of the
certificate/revocation information of each certificate being held in
certificate storage or in revocation information will then be checked. If the
current time, minus the value of 'safety_buffer', is greater than the
expiration, it will be removed.

Modifies the current configuration for automatic tidy execution.

const pathConfigAutoTidyDesc = `
This endpoint accepts parameters to a tidy operation (see /tidy) that
will be used for automatic tidy execution. This takes two extra parameters,
enabled (to enable or disable auto-tidy) and interval_duration (which
controls the frequency of auto-tidy execution).

Once enabled, a tidy operation will be kicked off automatically, as if it
were executed with the posted configuration.
