对于解密,操作是一样的。 在AesSetKey时,最后的参数需要传入 AES_DECRYPTION。 对数据的加解密,对于音频,因为数据量小,另外从中间截取就可以播放,所以需要全加密,而对于视频数据来说,因为数据量较大,而P帧的解析又依赖于I帧,同时在I帧中自身也有对数据的校验,所以只需要对I帧的前32个字节加密,就可以保证视频数据...
The AES-GCM128 core from Alma Technologies implements the GCM-AES authenticated encryption and decryption, as specified in the NIST SP800-38D recommendation for GCM and GMAC and the FIPS-197 Advanced Encryption Standard. The core can be programmed to encrypt or decrypt 128-bit blocks of data, ...
The decryption operation failed. Prior to .NET 8, indicates the tag value could not be verified. AuthenticationTagMismatchException .NET 8 and later versions: the tag value could not be verified. Remarks Iftagcannot be validated (using the key,nonce,ciphertext, andassociatedDatavalues), thenplain...
Edited by @vcsjones API Proposal: As the issue outlines below, this proposes changes to AesGcm because it's current design makes it prone to misuse of allowing truncated authentication tags during decryption. This proposes new constructo...

OpenSSL在AES-GCM中初始化向量的正确使用 、、、 我见过许多在OpenSSL中实现AES-GCM的例子,但它们都是加密和解密一条消息。How to properly change IV after decryption (using OpenSSL)? 有预定义的IV,并在解密后将其增加1,安全吗?如果是这样的话,OpenSSL...

在Python中,使用AES-GCM模式进行加密时,通常会生成一个认证标签(authentication tag),这个标签可以用来验证数据的完整性。当你解密数据时,如果认证标签不匹配,那么说明数据已经被篡改。 以下是一个使用cryptography库的示例代码,展示了如何验证AES-GCM加密后的数据的完整性: ...
