A biblioteca oferece uma grande cole\u00e7\u00e3o de primitivas prontas, utilizadas no protocolo TLS, certificados X.509, cifras AEAD, m\u00f3dulos TPM, PKCS#11, hash de senhas e criptografia p\u00f3s-qu\u00e2ntica (assinaturas baseadas em hash e acordo de chaves com base em McEliece).

O uso de \/proc e \/dev\/random para formar a entropia do gerador de n\u00fameros pseudo-aleat\u00f3rios foi interrompido.
