蜡梅和梅花的“成名”也分早晚。蜡梅在宋代才被普遍栽培为一种观赏植物,而梅花受人关注的时间更久远。1975年,我国考古人员在安阳殷墟商代铜鼎中发现了梅核,这说明早在3000多年前,梅已用作食品。汉初,梅花就已经成为一种观赏性植物。《西京杂记》载:“汉初修上林苑,远方各献名果异树,有朱梅、胭脂梅”。

The objective is a tall order. The quantum-resistant cryptographic data needed to transparently publish TLS certificates is roughly 40 times bigger than the classical cryptographic material used today. Today’s X.509 certificates are about 64 bytes in size, and comprise six elliptic curve signatures and two EC public keys. This material can be cracked through the quantum-enabled Shor’s algorithm. Certificates containing the equivalent quantum-resistant cryptographic material are roughly 2.5 kilobytes. All this data must be transmitted when a browser connects to a site.
