The required_rubygems_version constraint for this specification

A fallback is included because the original version of the specification API didn’t include that field, so some marshalled specs in the index have it set to nil.

The required_rubygems_version constraint for this specification

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

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.

Close this handle.

Calling close more than once will raise a Fiddle::DLError exception.

Array of the currently loaded libraries.

Allocates a C struct with the types provided.

See Fiddle::Pointer.malloc for memory management issues.

Examples

# Automatically freeing the pointer when the block is exited - recommended
Fiddle::Pointer.malloc(size, Fiddle::RUBY_FREE) do |pointer|
  ...
end

# Manually freeing but relying on the garbage collector otherwise
pointer = Fiddle::Pointer.malloc(size, Fiddle::RUBY_FREE)
...
pointer.call_free

# Relying on the garbage collector - may lead to unlimited memory allocated before freeing any, but safe
pointer = Fiddle::Pointer.malloc(size, Fiddle::RUBY_FREE)
...

# Only manually freeing
pointer = Fiddle::Pointer.malloc(size)
begin
  ...
ensure
  Fiddle.free pointer
end

# No free function and no call to free - the native memory will leak if the pointer is garbage collected
pointer = Fiddle::Pointer.malloc(size)
...

Allocate size bytes of memory and associate it with an optional freefunc.

If a block is supplied, the pointer will be yielded to the block instead of being returned, and the return value of the block will be returned. A freefunc must be supplied if a block is.

If a freefunc is supplied it will be called once, when the pointer is garbage collected or when the block is left if a block is supplied or when the user calls call_free, whichever happens first. freefunc must be an address pointing to a function or an instance of Fiddle::Function.

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.

Examples

OpenSSL::Digest.digest("SHA256", "abc")

which is equivalent to:

OpenSSL::Digest.digest('SHA256', "abc")

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.

Example

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.

Example

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.

Example

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.

Example

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.
