Reads the file from pathname, then parses it like ::parse, returning the root node of the abstract syntax tree.

SyntaxError is raised if pathname’s contents are not valid Ruby syntax.

RubyVM::AbstractSyntaxTree.parse_file("my-app/app.rb")
# => #<RubyVM::AbstractSyntaxTree::Node:SCOPE@1:0-31:3>

See ::parse for explanation of keyword argument meaning and usage.

Returns the length of the hash value of the digest.

This method should be overridden by each implementation subclass. If not, digest_obj.digest().length() is returned.

Returns the block length of the digest.

This method is overridden by each implementation subclass.

Similar to decode with the difference that decode expects one distinct value represented in der. decode_all on the contrary decodes a sequence of sequential BER/DER values lined up in der and returns them as an array.

Example

ders = File.binread('asn1data_seq')
asn1_ary = OpenSSL::ASN1.decode_all(ders)

Returns the integer representing length of the value of field 'Content-Range', or nil if no such field exists; see Content-Range response header:

res = Net::HTTP.get_response(hostname, '/todos/1')
res['Content-Range'] # => nil
res['Content-Range'] = 'bytes 0-499/1000'
res.range_length     # => 500

Returns true if the current platform has saved user ID functionality.
