Generates a random prime number of bit length bits. If safe is set to true
, generates a safe prime. If add is specified, generates a prime that fulfills condition p % add = rem
.
Generate a random key with OpenSSL::Random.random_bytes
and sets it to the cipher, and returns it.
You must call encrypt
or decrypt
before calling this method.

Parses the configuration data read from io and returns the whole content as a Hash
.
Emit a scalar with value
and tag
Called with encoding
when the YAML
stream starts. This method is called once per stream. A stream may contain multiple documents.
See the constants in Psych::Parser
for the possible values of encoding
.
Called when the document starts with the declared version
, tag_directives
, if the document is implicit
.
version
will be an array of integers indicating the YAML
version being dealt with, tag_directives
is a list of tuples indicating the prefix and suffix of each tag, and implicit
is a boolean indicating whether the document is started implicitly.
Given the following YAML:
%YAML 1.1 %TAG ! tag:tenderlovemaking.com,2009: --- !squee
The parameters for start_document
must be this:
version # => [1, 1] tag_directives # => [["!", "tag:tenderlovemaking.com,2009:"]] implicit # => false
Called when a sequence is started.
anchor
is the anchor associated with the sequence or nil. tag
is the tag associated with the sequence or nil. implicit
a boolean indicating whether or not the sequence was implicitly started. style
is an integer indicating the list style.
See the constants in Psych::Nodes::Sequence
for the possible values of style
.
Here is a YAML
document that exercises most of the possible ways this method can be called:
--- - !!seq [ a ] - &pewpew - b
The above YAML
document consists of three lists, an outer list that contains two inner lists. Here is a matrix of the parameters sent to represent these lists:
# anchor tag implicit style [nil, nil, true, 1 ] [nil, "tag:yaml.org,2002:seq", false, 2 ] ["pewpew", nil, true, 1 ]
