# SSL context options

SSL context options — SSL context option listing

### 설명

### 옵션

`verify_peer` boolean

  Require verification of SSL certificate used.

  Defaults to `FALSE`.

`allow_self_signed` boolean

  Allow self-signed certificates.

  Defaults to `FALSE`

`cafile` string

  Location of Certificate Authority file on local filesystem which should be used with the verify_peer context option to authenticate the identity of the remote peer.

`capath` string

  If cafile is not specified or if the certificate is not found there, the directory pointed to by capath is searched for a suitable certificate. capath must be a correctly hashed certificate directory.

`passphrase` string

  Passphrase with which your local_cert file was encoded.

  Abort if the certificate chain is too deep.

  Defaults to no verification.

`ciphers` string

  Sets the list of available ciphers. The format of the string is described in » ciphers(1).

  Defaults to DEFAULT.

`capture_peer_cert` boolean

  If set to `TRUE` a peer_certificate context option will be created containing the peer certificate.

`capture_peer_chain` boolean

  If set to `TRUE` a peer_certificate_chain context option will be created containing the certificate chain.
