The mode needed to read a file as straight binary.
Returns a list of paths matching glob that can be used by a gem to pick up features from other gems. For example:
Gem.find_files('rdoc/discover').each do |path| load path end
if check_load_path is true (the default), then find_files also searches $LOAD_PATH for files as well as gems.
Note that find_files will return all files even if they are from different versions of the same gem. See also find_latest_files
Adds a post-build hook that will be passed an Gem::Installer instance when Gem::Installer#install is called. The hook is called after the gem has been extracted and extensions have been built but before the executables or gemspec has been written. If the hook returns false then the gem’s files will be removed and the install will be aborted.
Adds a hook that will get run after Gem::Specification.reset is run.
Safely read a file in binary mode on all platforms.

Returns an estimate of the resolution of a clock_id using the POSIX clock_getres() function.
Note the reported resolution is often inaccurate on most platforms due to underlying bugs for this function and therefore the reported resolution often differs from the actual resolution of the clock in practice. Inaccurate reported resolutions have been observed for various clocks including CLOCK_MONOTONIC and CLOCK_MONOTONIC_RAW when using Linux, macOS, BSD or AIX platforms, when using ARM processors, or when using virtualization.
clock_id specifies a kind of clock. See the document of Process.clock_gettime for details. clock_id can be a symbol as for Process.clock_gettime.
If the given clock_id is not supported, Errno::EINVAL is raised.
unit specifies the type of the return value. Process.clock_getres accepts unit as Process.clock_gettime. The default value, :float_second, is also the same as Process.clock_gettime.
Process.clock_getres also accepts :hertz as unit. :hertz means the reciprocal of :float_second.
:hertz can be used to obtain the exact value of the clock ticks per second for the times() function and CLOCKS_PER_SEC for the clock() function.
Process.clock_getres(:TIMES_BASED_CLOCK_PROCESS_CPUTIME_ID, :hertz) returns the clock ticks per second.
Process.clock_getres(:CLOCK_BASED_CLOCK_PROCESS_CPUTIME_ID, :hertz) returns CLOCKS_PER_SEC.
p Process.clock_getres(Process::CLOCK_MONOTONIC) #=> 1.0e-09
This integer returns the current initial length of the buffer.
This sets the initial length of the buffer to length, if length > 0, otherwise its value isn’t changed.
Returns debugging information about this node as a string.
Indicates whether this DH instance has a private key associated with it or not. The private key may be retrieved with DH#priv_key.
Indicates whether this DSA instance has a private key associated with it or not. The private key may be retrieved with DSA#private_key.
Verifies whether the signature is valid given the message digest input. It does so by validating sig using the public key of this DSA instance.
digest is a message digest of the original input data to be signed
sig is a DSA signature value
dsa = OpenSSL::PKey::DSA.new(2048) doc = "Sign me" digest = OpenSSL::Digest.digest('SHA1', doc) sig = dsa.syssign(digest) puts dsa.sysverify(digest, sig) # => true
Returns whether this EC instance has a private key. The private key (BN) can be retrieved with EC#private_key.
