Results for: "String#[]"

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

If a block is given, returns a lazy enumerator that will iterate over the given block for each element with an index, which starts from offset, and returns a lazy enumerator that yields the same values (without the index).

If a block is not given, returns a new lazy enumerator that includes the index, starting from offset.

offset

the starting index to use

See Enumerator#with_index.

Return the block length of the digest in bytes.

Return the block length of the digest in bytes.

Digest::SHA256.new.block_length * 8
# => 512
Digest::SHA384.new.block_length * 8
# => 1024
Digest::SHA512.new.block_length * 8
# => 1024

Returns the Fiddle::Pointer of this handle.

Get the underlying pointer for ruby object val and return it as a Fiddle::Pointer object.

Returns the integer memory location of this pointer.

Generates a cryptographically strong pseudo-random number in the range 0…range.

See also the man page BN_rand_range(3).

Generates a random prime number of bit length bits. If safe is set to true, generates a safe prime. If add is specified, generates a prime that fulfills condition p % add = rem.

Parameters

• bits - integer

• safe - boolean

• add - BN

• rem - BN

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.

Example

digest = OpenSSL::Digest.new('SHA1')
puts digest.block_length # => 64

Sends the given command to this engine.

Raises an EngineError if the command fails.
