Advanced Encryption Standard (AES), también conocido como Rijndael (pronunciado "Rain Doll" en inglés), es un esquema de cifrado por bloques adoptado como un estándar de cifrado por el gobierno de los Estados Unidos, creado en Bélgica.El AES fue anunciado por el Instituto Nacional de Estándares y Tecnología (NIST) como FIPS PUB 197 de los Estados Unidos (FIPS 197) el 26 de noviembre de The Version table provides details related to the release that this issue/RFE will be addressed.

Quote; Even after disabling The Advanced Encryption Standard (AES), also known by its original name Rijndael (Dutch pronunciation: [ˈrɛindaːl]), is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001.. AES is a subset of the Rijndael block cipher developed by two Belgian cryptographers, Vincent Rijmen and Joan Daemen, who submitted In the above example AES_128_GCM forms the cipher. AES is the preferred algorithm and using a key size of 128bits is acceptable. You can prefer 128bit keys over 256bit keys for performance reasons.

I tested it to be working on Linux (using Mono "Strong encryption" is, and has always been, a moving target. Furthermore, the definition of "strong" depends on your desired use cases, your threat models, and your acceptable levels of risk. The Apache HTTP Server team cannot determine these things for you.

@false Yeah, I've read that but the answer was to update OpenSSL or update Ruby to use an updated OpenSSL version that supports GCM. I have both: Ruby reports using OpenSSL 1.1.0 and OpenSSL reports having gcm ciphers. The encryption key size generated in the above code is 256 bits (32 bytes) and it configures the AES-GCM cipher as AES-256-GCM. If we change the key size to 128 bits or 192 bits, we shall use AES-128-GCM or AES-192-GCM respectively. The output from the above code looks like this: AES is a symmetric key encryption cipher, and it is generally regarded as the "gold standard” for encrypting data.. AES is NIST-certified and is used by the US government for protecting "secure” data, which has led to a more general adoption of AES as the standard symmetric key cipher of choice by just about everyone. For C#, to achieve AES 256 GCM encryption, I used Bouncy Castle cryptographic libraries.

*RSA_AES_128_GCM_SHA256 Use the Rivest Shamir Adleman (RSA) public key algorithm with the Advanced Encryption Standard (AES) cipher with Galois/Counter mode (GCM) and 128 bit keys. Use Secure Hash Algorithm 256 (SHA256) for generating the message authentication code (MAC).
