Like Enumerable#reject, but chains operation to be lazy-evaluated.
Like Enumerable#grep, but chains operation to be lazy-evaluated.

Like Enumerable#zip, but chains operation to be lazy-evaluated. However, if a block is given to zip, values are enumerated immediately.

Like Enumerable#drop, but chains operation to be lazy-evaluated.
Like Enumerable#uniq, but chains operation to be lazy-evaluated.
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.
Generate a random IV 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, see also parse.
Raises a ConfigError on invalid configuration data.
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.
