Returns a string containing a character to be appended on completion. The default is a space (“ ”).

Raises NotImplementedError if the using readline library does not support.

When called during a completion (e.g. from within your completion_proc), it will return a string containing the character used to quote the argument being completed, or nil if the argument is unquoted.

When called at other times, it will always return nil.

Note that Readline.completer_quote_characters must be set, or this method will always return nil.

Sets a list of quote characters which can cause a word break.

Raises NotImplementedError if the using readline library does not support.

Gets a list of quote characters which can cause a word break.

Raises NotImplementedError if the using readline library does not support.

Sets a list of characters which can be used to quote a substring of the line. Completion occurs on the entire substring, and within the substring Readline.completer_word_break_characters are treated as any other character, unless they also appear within this list.

Raises NotImplementedError if the using readline library does not support.

Gets a list of characters which can be used to quote a substring of the line.

Raises NotImplementedError if the using readline library does not support.

Sets a list of characters that cause a filename to be quoted by the completer when they appear in a completed filename. The default is nil.

Raises NotImplementedError if the using readline library does not support.

Gets a list of characters that cause a filename to be quoted by the completer when they appear in a completed filename.

Raises NotImplementedError if the using readline library does not support.

Default options for gem commands for Ruby packagers.

The options here should be structured as an array of string “gem” command names as keys and a string of the default options as values.

Example:

def self.operating_system_defaults

{
    'install' => '--no-rdoc --no-ri --env-shebang',
    'update' => '--no-rdoc --no-ri --env-shebang'
}

end

Should be implemented by a extended class.

tsort_each_node is used to iterate for all nodes over a graph.

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.

Writes string to the SSL connection in a non-blocking manner. Raises an SSLError if writing would block.

Checks the nonce validity for this request and response.

The return value is one of the following:

-1

nonce in request only.

0

nonces both present and not equal.

1

nonces present and equal.

2

nonces both absent.

3

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.

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.

Raises an exception if the key is invalid.

See the OpenSSL documentation for EC_KEY_check_key()

Signs data using the Probabilistic Signature Scheme (RSA-PSS) and returns the calculated signature.

RSAError will be raised if an error occurs.

See verify_pss for the verification operation.

Parameters

digest

A String containing the message digest algorithm name.

data

A String. The data to be signed.

salt_length

The length in octets of the salt. Two special values are reserved: :digest means the digest length, and :max means the maximum possible length for the combination of the private key and the selected message digest algorithm.

mgf1_hash

The hash algorithm used in MGF1 (the currently supported mask generation function (MGF)).

Example

data = "Sign me!"
pkey = OpenSSL::PKey::RSA.new(2048)
signature = pkey.sign_pss("SHA256", data, salt_length: :max, mgf1_hash: "SHA256")
pub_key = pkey.public_key
puts pub_key.verify_pss("SHA256", signature, data,
                        salt_length: :auto, mgf1_hash: "SHA256") # => true

Verifies data using the Probabilistic Signature Scheme (RSA-PSS).

The return value is true if the signature is valid, false otherwise. RSAError will be raised if an error occurs.

See sign_pss for the signing operation and an example code.

Parameters

digest

A String containing the message digest algorithm name.

data

A String. The data to be signed.

salt_length

The length in octets of the salt. Two special values are reserved: :digest means the digest length, and :auto means automatically determining the length based on the signature.

mgf1_hash

The hash algorithm used in MGF1.
