Like Enumerable#zip, but chains operation to be lazy-evaluated. However, if a block is given to zip, values are enumerated immediately.
Returns the number that defines the common difference between two adjacent elements in this arithmetic sequence.
Returns the first number in this arithmetic sequence, or an array of the first n elements.
Returns the last number in this arithmetic sequence, or an array of the last n elements.
Returns the hash value of a given string. This is equivalent to Digest::Class.new(*parameters).digest(string), where extra parameters, if any, are passed through to the constructor and the string is passed to digest().
Returns the hex-encoded hash value of a given string. This is almost equivalent to Digest.hexencode(Digest::Class.new(*parameters).digest(string)).
Returns the base64 encoded hash value of a given string. The return value is properly padded with ‘=’ and contains no line feeds.
Returns a new Fiddle::Pointer instance that is a dereferenced pointer for this pointer.
Analogous to the star operator in C.
Wakes up all threads waiting for this lock.
Performs a Miller-Rabin probabilistic primality test with checks iterations. If checks is not specified, a number of iterations is used that yields a false positive rate of at most 2^-80 for random input.
checks - integer
Returns the names of all available ciphers in an array.
Return the hash value computed with name Digest. name is either the long name or short name of a supported digest algorithm.
OpenSSL::Digest.digest("SHA256", "abc")
which is equivalent to:
OpenSSL::Digest::SHA256.digest("abc")
Returns a new instance of OpenSSL::Cipher by name, if it is available in this engine.
An EngineError will be raised if the cipher is unavailable.
e = OpenSSL::Engine.by_id("openssl")
=> #<OpenSSL::Engine id="openssl" name="Software engine support">
e.cipher("RC4")
=> #<OpenSSL::Cipher:0x007fc5cacc3048>
Returns a new instance of OpenSSL::Digest by name.
Will raise an EngineError if the digest is unavailable.
e = OpenSSL::Engine.by_id("openssl") #=> #<OpenSSL::Engine id="openssl" name="Software engine support"> e.digest("SHA1") #=> #<OpenSSL::Digest: da39a3ee5e6b4b0d3255bfef95601890afd80709> e.digest("zomg") #=> OpenSSL::Engine::EngineError: no such digest `zomg'
Returns the authentication code as a binary string. The digest parameter specifies the digest algorithm to use. This may be a String representing the algorithm name or an instance of OpenSSL::Digest.
key = 'key' data = 'The quick brown fox jumps over the lazy dog' hmac = OpenSSL::HMAC.digest('sha1', key, data) #=> "\xDE|\x9B\x85\xB8\xB7\x8A\xA6\xBC\x8Az6\xF7\n\x90p\x1C\x9D\xB4\xD9"
Returns the authentication code as a hex-encoded string. The digest parameter specifies the digest algorithm to use. This may be a String representing the algorithm name or an instance of OpenSSL::Digest.
key = 'key' data = 'The quick brown fox jumps over the lazy dog' hmac = OpenSSL::HMAC.hexdigest('sha1', key, data) #=> "de7c9b85b8b78aa6bc8a7a36f70a90701c9db4d9"
Returns the authentication code an instance represents as a binary string.
instance = OpenSSL::HMAC.new('key', OpenSSL::Digest.new('sha1')) #=> f42bb0eeb018ebbd4597ae7213711ec60760843f instance.digest #=> "\xF4+\xB0\xEE\xB0\x18\xEB\xBDE\x97\xAEr\x13q\x1E\xC6\a`\x84?"
Returns the authentication code an instance represents as a hex-encoded string.
Returns the exit status of the child for which PTY#check raised this exception
