如果这些信息仍然通过 2048 位 RSA 加密或类似的方式发送,那么这些组织就应该开始担心了。 -End- 编辑:李亚山 参考:https://www.technologyreview.com/s/613596/how-a-quantum-computer-could-break-2048-bit-rsa-encryption-in-8-hours/
只要密钥长度足够长,用RSA加密的信息实际上是不能被解破的。目前一般为1024 bit以上的密钥,推荐2048 bit以上。 对称加密vs分对称加密? 对称加密是最快速、最简单的一种加密方式,加密(encryption)与解密(decryption)用的是同样的密钥(secret key)。对称加密有很多种算法,由于它效率很高,所以被广泛使用在很多加密协议...

1.对称加密标准 encryption standard AES (Advanced Encryption Standard)高级加密标准。Rijndael算法首先是一个密钥分组加密的算法,通过置换(permutations )和替换(substitutions)迭代加密,进过多轮操作形成密文。AES算是Rijndael算法的一种特殊实现,选的分组为128bit(16字节),密钥可以使用128、192 和 256bit三种。 AES是...
pkcs1padding V1.5是RSA加解密默认的填充方式。在进行RSA运算时需要将源数据D转化为Encryption block(EB)。其中pkcs1padding V1.5的填充模式按照以下方式进行。 EB = 00 + BT + PS + 00 + D 1. EB:为填充后的16进制加密数据块,长度为1024/8 = 128字节(密钥长度1024位的情况下) ...

For ordinary people, there is little risk. Most people use 2048-bit encryption, or something similar, for tasks like sending credit card details over the internet. If these transactions are recorded today and broken in 25 years, little will be lost. ...

If the third party does not know the private key of the real sender, the digital signature generated after encryption is different from the recalculated digital signature. In this way, the authenticity of the digital signature is guaranteed. Collezioni Scarica il documento Ultimo aggiornamento:2025...
SHA-256:不是加解密算法,是一个安全Hash算法。可用于确认数据的完整性。可称为one way encryption,不存在相应的解密算法。 AES-256:为对称块加密算法,用于消息的加解密。可对大量数据同时进行加解密。计算速度快于RSA。加密和解密使用相同的密钥key。
