这是另一个不使用分离签名的工作示例。要对此进行测试,只需将 'user@host.name' 更改为密钥的标识符并执行以下操作: GPG.decrypt(GPG.encrypt('some text', :armor => true))
require 'gpgme'
require 'highline/import'
module GPG
ENCRYPT_KEY = 'user@host.com'
@gpg = GPGME::Crypto.new
class << self
def decrypt(encrypted_data, options = {})
options = { :passphrase_callback => self.method(:passfunc) }.merge(options)
@gpg.decrypt(encrypted_data, options).read
end
def encrypt(data_to_encrypt, options = {})
options = { :passphrase_callback => self.method(:passfunc), :armor => true }.merge(options)
@gpg.encrypt(data_to_encrypt, options).read
end
private
def get_passphrase
ask("Enter passphrase for #{ENCRYPT_KEY}: ") { |q| q.echo = '*' }
end
def passfunc(hook, uid_hint, passphrase_info, prev_was_bad, fd)
begin
system('stty -echo')
io = IO.for_fd(fd, 'w')
io.puts(get_passphrase)
io.flush
ensure
(0 ... $_.length).each do |i| $_[i] = ?0 end if $_
system('stty echo')
end
$stderr.puts
end
end
end
