AEAD_AES_256_GCM 使用 AES-256 进行加密,并附加了 GCM(Galois/Counter Mode)模式,以提供认证和完整性检查。这意味着解密过程不仅需要密钥和密文,还需要附加认证数据(AAD)和非密文数据(如标签或 MAC)来验证数据的完整性。 2. 准备 PHP 环境 确保你的 PHP 环境中安装了 OpenSSL 扩展。你可以通过运行 php -m...

官方给的demo中需要用到PHP7.0以上才支持的sodium_crypto_aead_aes256gcm_decrypt方法 但因为我们系统代码量比较厚重,如果升级会是个很大的工程量,所以尝试了Sodium Compat PHP 类库。但这个类库的底层用的是openssl_decrpt方法,并声明了该方法不支持php7.0以下 请问有折中的实现方式吗回答关注问题邀请回答 收藏 分享 ...
.NET CORE 3.1 AEAD_AES_256_GCM解密微信平台证书 对接微信支付V3的接口,可以算是从1开始踩坑,多的不说,先记录一下这个平台证书的问题。 在拿到这个AEAD_AES_256_GCM加密后的证书内容,需要去做解密,这个时候很尴尬的,微信这边仅仅提供了php和java版本的。 而我是.NET CORE3.1版本的 找了半天资料,很容易发现...

Returns true if it is safe to encrypt with AES-256-GCM, and false otherwise. User Contributed Notes 1 note up down 1 Soatok Dreamseeker ¶ 1 year ago The reason libsodium has an "is_available()" API for AES-GCM and not the ChaCha-Poly AEAD ciphers is that, unlike OpenSSL, ...
