Results for: "String# "

Finishes the digest and returns the resulting hash value.

This method is overridden by each implementation subclass and often made private, because some of those subclasses may leave internal data uninitialized. Do not call this method from outside. Use digest!() instead, which ensures that internal data be reset for security reasons.

Creates a printable version of the digest object.

If none is given, returns the resulting hash value of the digest, keeping the digest’s state.

If a string is given, returns the hash value for the given string, resetting the digest to the initial state before and after the process.

Returns the resulting hash value and resets the digest to the initial state.

If none is given, returns the resulting hash value of the digest in a hex-encoded form, keeping the digest’s state.

If a string is given, returns the hash value for the given string in a hex-encoded form, resetting the digest to the initial state before and after the process.

Returns the resulting hash value in a hex-encoded form and resets the digest to the initial state.

Returns digest_obj.digest_length().

If none is given, returns the resulting hash value of the digest in a base64 encoded form, keeping the digest’s state.

If a string is given, returns the hash value for the given string in a base64 encoded form, resetting the digest to the initial state before and after the process.

In either case, the return value is properly padded with ‘=’ and contains no line feeds.

Returns the resulting hash value and resets the digest to the initial state.

If a block is given, it prints out each of the elements encountered. Block parameters are (in that order):

• depth: The recursion depth, plus one with each constructed value being encountered (Integer)

• offset: Current byte offset (Integer)

• header length: Combined length in bytes of the Tag and Length headers. (Integer)

• length: The overall remaining length of the entire data (Integer)

• constructed: Whether this value is constructed or not (Boolean)

• tag_class: Current tag class (Symbol)

• tag: The current tag number (Integer)

Example

der = File.binread('asn1data.der')
OpenSSL::ASN1.traverse(der) do | depth, offset, header_len, length, constructed, tag_class, tag|
  puts "Depth: #{depth} Offset: #{offset} Length: #{length}"
  puts "Header length: #{header_len} Tag: #{tag} Tag class: #{tag_class} Constructed: #{constructed}"
end

Reads lines from the stream which are separated by eol.

See also gets

Reads a line from the stream which is separated by eol.

Raises EOFError if at end of file.

Pushes character c back onto the stream such that a subsequent buffered character read will return it.

Unlike IO#getc multiple bytes may be pushed back onto the stream.

Has no effect on unbuffered reads (such as sysread).

Writes s to the stream. If the argument is not a String it will be converted using .to_s method. Returns the number of bytes written.

Return true if the PRNG has been seeded with enough data, false otherwise.

Start streaming using encoding

See IO#write

Returns an array of Range objects that represent the value of field 'Range', or nil if there is no such field; see Range request header:

req = Net::HTTP::Get.new(uri)
req['Range'] = 'bytes=0-99,200-299,400-499'
req.range # => [0..99, 200..299, 400..499]
req.delete('Range')
req.range # # => nil

Adds a separated list. The list is separated by comma with breakable space, by default.

seplist iterates the list using iter_method. It yields each object to the block given for seplist. The procedure separator_proc is called between each yields.

If the iteration is zero times, separator_proc is not called at all.

If separator_proc is nil or not given, +lambda { comma_breakable }+ is used. If iter_method is not given, :each is used.

For example, following 3 code fragments has similar effect.

q.seplist([1,2,3]) {|v| xxx v }

q.seplist([1,2,3], lambda { q.comma_breakable }, :each) {|v| xxx v }

xxx 1
q.comma_breakable
xxx 2
q.comma_breakable
xxx 3

Generate a random alphanumeric string.

The argument n specifies the length, in characters, of the alphanumeric string to be generated. The argument chars specifies the character list which the result is consist of.

If n is not specified or is nil, 16 is assumed. It may be larger in the future.

The result may contain A-Z, a-z and 0-9, unless chars is specified.

require 'random/formatter'

Random.alphanumeric     #=> "2BuBuLf3WfSKyQbR"
# or
prng = Random.new
prng.alphanumeric(10) #=> "i6K93NdqiH"

Random.alphanumeric(4, chars: [*"0".."9"]) #=> "2952"
# or
prng = Random.new
prng.alphanumeric(10, chars: [*"!".."/"]) #=> ",.,++%/''."
