Web27 de fev. de 2014 · The CHACHA20-POLY1305 Authenticated Encryption with Associated Data (AEAD) construction, described in Section 2.8 . This document does not introduce these new algorithms for the first time. They have been defined in scientific papers by D. J. Bernstein, which are referenced by this document. Web9 de mar. de 2024 · On Wednesday, March 6, the OpenSSL team revealed a low severity vulnerability in the ChaCha20-Poly1305, an AEAD cipher that incorrectly allows a nonce to be set of up to 16 bytes. OpenSSL team states that ChaCha20-Poly1305 requires a unique nonce input for every encryption operation.

With all other things being equal, you will use it if its a common cipher and its selected by the client or server. If you are not seeing ChaCha20/Poly1305 as the cipher suite, then check the server. It probably lacks support for curve25519 or the cipher suite.
Authenticated encryption with ChaCha20-Poly1305. Like EVP_chacha20 (), the key is 256 bits and the IV is 96 bits.
