Lint/DeprecatedOpenSSLConstant suggestion with double quoted string

[tsugimoto]

a.rb:2:3: W: Lint/DeprecatedOpenSSLConstant: Use OpenSSL::Cipher.new('AES-256-cbc') instead of OpenSSL::Cipher::AES256.new('cbc').
  OpenSSL::Cipher::AES256.new('cbc')
  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
a.rb:5:3: W: Lint/DeprecatedOpenSSLConstant: Use OpenSSL::Cipher.new('AES-256-"cbc"') instead of OpenSSL::Cipher::AES256.new("cbc").
  OpenSSL::Cipher::AES256.new("cbc")
  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The suggestion is valid with single quoted strings, but broken with double quoted ones.

Expected behavior

Suggestion should be OpenSSL::Cipher::AES256.new("AES-256-cbc") (preserving double quotes) at least, or one of the OpenSSL::Cipher.ciphers entries if we really want consistent casing.

Actual behavior

OpenSSL::Cipher.new('AES-256-"cbc"') does not exist.

Steps to reproduce the problem

do_something do
  OpenSSL::Cipher::AES256.new("cbc")
end

and

$ rubocop --only Lint/DeprecatedOpenSSLConstant

RuboCop version

$ rubocop -V
0.84.0 (using Parser 2.7.1.2, rubocop-ast 0.0.3, running on ruby 2.6.3 x86_64-darwin18)

And I've just found that it actually tries to concatenate non-strings:

FOO = "cbc"
do_something do
  OpenSSL::Cipher::AES256.new(FOO)
end

a.rb:3:3: W: Lint/DeprecatedOpenSSLConstant: Use OpenSSL::Cipher.new('AES-256-FOO') instead of OpenSSL::Cipher::AES256.new(FOO).
  OpenSSL::Cipher::AES256.new(FOO)
  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
