Set
the default id conversion object.
This is expected to be an instance such as DRb::DRbIdConv
that responds to to_id
and to_obj
that can convert objects to and from DRb
references.
See DRbServer#default_id_conv.
Attempts to enter exclusive section. Returns false
if lock fails.
For backward compatibility
Should be implemented by a extended class.
tsort_each_node
is used to iterate for all nodes over a graph.
Should be implemented by a extended class.
tsort_each_child
is used to iterate for child nodes of node.
Returns the security level for the context.
See also OpenSSL::SSL::SSLContext#security_level=
.
Sets the security level for the context. OpenSSL
limits parameters according to the level. The “parameters” include: ciphersuites, curves, key sizes, certificate signature algorithms, protocol version and so on. For example, level 1 rejects parameters offering below 80 bits of security, such as ciphersuites using MD5 for the MAC or RSA keys shorter than 1024 bits.
Note that attempts to set such parameters with insufficient security are also blocked. You need to lower the level first.
This feature is not supported in OpenSSL
< 1.1.0, and setting the level to other than 0 will raise NotImplementedError
. Level 0 means everything is permitted, the same behavior as previous versions of OpenSSL
.
See the manpage of SSL_CTX_set_security_level(3) for details.
Initiates the SSL/TLS handshake as a server in non-blocking manner.
# emulates blocking accept begin ssl.accept_nonblock rescue IO::WaitReadable IO.select([s2]) retry rescue IO::WaitWritable IO.select(nil, [s2]) retry end
By specifying a keyword argument exception to false
, you can indicate that accept_nonblock
should not raise an IO::WaitReadable
or IO::WaitWritable
exception, but return the symbol :wait_readable
or :wait_writable
instead.
A non-blocking version of sysread
. Raises an SSLError
if reading would block. If “exception: false” is passed, this method returns a symbol of :wait_readable, :wait_writable, or nil, rather than raising an exception.
Reads length bytes from the SSL
connection. If a pre-allocated buffer is provided the data will be written into it.
The X509
certificate for this socket’s peer.
The short name of the ObjectId
, as defined in <openssl/objects.h>.
The long name of the ObjectId
, as defined in <openssl/objects.h>.
Adds a nonce to the OCSP
request. If no nonce is given a random one will be generated.
The nonce is used to prevent replay attacks but some servers do not support it.
Checks the nonce validity for this request and response.
The return value is one of the following:
nonce in request only.
nonces both present and not equal.
nonces present and equal.
nonces both absent.
nonce present in response only.
For most responses, clients can check result > 0. If a responder doesn’t handle nonces result.nonzero?
may be necessary. A result of 0
is always an error.
Copies the nonce from request into this response. Returns 1 on success and 0 on failure.
Adds nonce to this response. If no nonce was provided a random nonce will be added.
Returns a SingleResponse
whose CertId matches with certificate_id, or nil
if this BasicResponse
does not contain it.
Checks the validity of thisUpdate and nextUpdate fields of this SingleResponse
. This checks the current time is within the range thisUpdate to nextUpdate.
It is possible that the OCSP
request takes a few seconds or the time is not accurate. To avoid rejecting a valid response, this method allows the times to be within nsec seconds of the current time.
Some responders don’t set the nextUpdate field. This may cause a very old response to be considered valid. The maxsec parameter can be used to limit the age of responses.
Returns the status of the certificate identified by the certid. The return value may be one of these constant:
V_CERTSTATUS_GOOD
V_CERTSTATUS_REVOKED
V_CERTSTATUS_UNKNOWN
When the status is V_CERTSTATUS_REVOKED, the time at which the certificate was revoked can be retrieved by revocation_time
.
