WebGenerates a string of pseudo-random bytes, with the number of bytes determined by the length parameter. It also indicates if a cryptographically strong algorithm was used to produce the pseudo-random bytes, and does this via the optional crypto_strong parameter. It's rare for this to be FALSE, but some systems may be broken or old. WebMay 29, 2016 · Cryptographically Secure Randomness in Java Aside from just using libsodium (recommended), Java's SecureRandom class is straightforward: SecureRandom csprng = new SecureRandom (); byte [] randomBytes = new byte [ 32 ]; csprng.nextBytes (randomBytes); Important: Despite its name, don't use SecureRandom.getInstanceStrong ()!

Webencrypt() 函数中，使用 crypto/rand 生成随机字节序列作为初始化向量 (IV)。然后，使用 crypto/aes 中的 NewCipher() 函数创建一个加密器实例。之后，使用 aes.BlockSize() 获取加密器所采用的分组大小，把原始文本填充（padding）成分组大小的倍数。 WebAEAD’s typically require a nonce in addition to the key. For the purposes we require symmetric cryptography for, we need encryption to be stateless. Because of this we use random nonces. (Thus the AEAD must support random nonces) We currently construct a random nonce, and encrypt the data with it. The returned value is nonce encrypted data ...
