Disable a call to dlclose() when this handle is garbage collected.
Enable a call to dlclose() when this handle is garbage collected.
Returns true if dlclose() will be called when this handle is garbage collected.
See man(3) dlclose() for more info.
bn.clear_bit!(bit) -> self
Sets the key length of the cipher. If the cipher is a fixed length cipher then attempting to set the key length to any value other than the fixed value is an error.
Under normal circumstances you do not need to call this method (and probably shouldn’t).
See EVP_CIPHER_CTX_set_key_length for further information.
Returns the output size of the digest, i.e. the length in bytes of the final message digest result.
digest = OpenSSL::Digest::SHA1.new puts digest.digest_length # => 20
Returns the block length of the digest algorithm, i.e. the length in bytes of an individual block. Most modern algorithms partition a message to be digested into a sequence of fix-sized blocks that are processed consecutively.
digest = OpenSSL::Digest::SHA1.new puts digest.block_length # => 64
Set the defaults for this engine with the given flag.
These flags are used to control combinations of algorithm methods.
flag can be one of the following, other flags are available depending on your OS.
0xFFFF

Builds a methods for level meth.
Returns OS code number recorded in the gzip file header.
Returns true if stat is readable by the real user id of this process.
File.stat("testfile").readable_real? #=> true
If stat is readable by others, returns an integer representing the file permission bits of stat. Returns nil otherwise. The meaning of the bits is platform dependent; on Unix systems, see stat(2).
m = File.stat("/etc/passwd").world_readable? #=> 420 sprintf("%o", m) #=> "644"
Returns true if stat is writable by the real user id of this process.
File.stat("testfile").writable_real? #=> true
If stat is writable by others, returns an integer representing the file permission bits of stat. Returns nil otherwise. The meaning of the bits is platform dependent; on Unix systems, see stat(2).
m = File.stat("/tmp").world_writable? #=> 511 sprintf("%o", m) #=> "777"
Same as executable?, but tests using the real owner of the process.
The provided block is passed a header and field for each pair in the row and expected to return true or false, depending on whether the pair should be deleted.
This method returns the row for chaining.
Removes any column or row for which the block returns true. In the default mixed mode or row mode, iteration is the standard row major walking of rows. In column mode, iteration will yield two element tuples containing the column name and an Array of values for that column.
This method returns the table for chaining.
Routes method calls to the referenced remote object.
