HashChainEntry

Struct HashChainEntry 

Source
pub struct HashChainEntry {
    pub prev_hash: String,
    pub current_hash: String,
    pub entry: SqlAuditContext,
}
Expand description

带哈希链的审计日志条目。

每条记录包含:

  • prev_hash:上一条记录的 current_hash(首条为 GENESIS_HASH
  • current_hash:本条记录的 SHA-256 哈希(基于 prev_hash + entry 计算)
  • entry:原始审计上下文(已脱敏)

任何对历史记录的篡改都会导致 current_hash 与下一条记录的 prev_hash 不匹配, 从而被 verify_chain 检测出来。

Fields§

§prev_hash: String

上一条记录的哈希(首条为 GENESIS_HASH

§current_hash: String

本条记录的哈希(SHA-256 十六进制串,64 字符)

§entry: SqlAuditContext

原始审计上下文(已脱敏)
