Contact your intended conversation partner via some other authenticated channel, such as OpenPGP-signed email or over the phone. You should tell each other your fingerprints. (A fingerprint is a checksum that identifies an encryption key.) If the fingerprint matches, you should indicate in the dialog below that you have verified the fingerprint.
请通过其他可信的渠道（例如 OpenPGP 签名的电子邮件或拨打电话），与您要进行通信的另一方联系。你们应该互相告诉对方自己的指纹。（“指纹”用于标识加密密钥的校验和。）若指纹匹配，就在下方的对话框中指出双方已验证过指纹。
