Class Method Details

.Digest(name) ⇒ Object

Returns a Digest subclass by name

require 'openssl'

OpenSSL::Digest("MD5")
# => OpenSSL::Digest::MD5

Digest("Foo")
# => NameError: wrong constant name Foo

def Digest(name)
  OpenSSL::Digest.const_get(name)
end

.secure_compare(a, b) ⇒ Object

call-seq:

OpenSSL.secure_compare(string, string) -> boolean

Constant time memory comparison. Inputs are hashed using SHA-256 to mask the length of the secret. Returns true if the strings are identical, false otherwise.
