Like Enumerable#map
, but chains operation to be lazy-evaluated.
(1..Float::INFINITY).lazy.map {|i| i**2 } #=> #<Enumerator::Lazy: #<Enumerator::Lazy: 1..Infinity>:map> (1..Float::INFINITY).lazy.map {|i| i**2 }.first(3) #=> [1, 4, 9]
Like Enumerable#compact
, but chains operation to be lazy-evaluated.
Returns a printable version of the enumerator chain.
Returns a printable version of the product enumerator.
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.
Convert this arithmetic sequence to a printable form.
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 string formatted with an easily readable representation of the internal state of the pointer.
Wakes up all threads waiting for this lock.
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")
Returns the names of all available digests in an array.
Returns the authentication code an a Base64-encoded string.
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 as a Base64-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.base64digest('SHA1', key, data) #=> "3nybhbi3iqa8ino29wqQcBydtNk="
Returns the authentication code an instance represents as a binary string.
instance = OpenSSL::HMAC.new('key', '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.
