curl is part of the OS, at /usr/bin/curl. Here's what I get on Big Sur 11.3.1:

	% curl --version
	curl 7.64.1 (x86_64-apple-darwin20.0) libcurl/7.64.1 (SecureTransport) LibreSSL/2.8.3 zlib/1.2.11 nghttp2/1.41.0
	Release-Date: 2019-03-27
	Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp smb smbs smtp smtps telnet tftp 
	Features: AsynchDNS GSS-API HTTP2 HTTPS-proxy IPv6 Kerberos Largefile libz MultiSSL NTLM NTLM_WB SPNEGO SSL UnixSockets

so it's SSL-enabled.

wget is not part of the OS, it's compiled by Dick Koch and installed by MacTeX, at /Library/TeX/Root/tlpkg/installer/wget/wget.<arch>. Here's what I get with MacTeX 2021:

	% /usr/local/texlive/2021/tlpkg/installer/wget/wget.universal-darwin --version
	GNU Wget 1.21 built on darwin20.2.0.

	-cares +digest -gpgme -https +ipv6 -iri +large-file -metalink -nls 
	-ntlm +opie -psl -ssl 

	Wgetrc: 
	    /usr/local/etc/wgetrc (system)
	Compile: 
	    gcc -DHAVE_CONFIG_H -DSYSTEM_WGETRC="/usr/local/etc/wgetrc" 
	    -DLOCALEDIR="/usr/local/share/locale" -I. -I../lib -I../lib 
	    -DNDEBUG -g -O2 
	Link: 
	    gcc -DNDEBUG -g -O2 ftp-opie.o ../lib/libgnu.a -liconv

where the "-ssl" seems to say it's been compiled without SSL support. Indeed, "/usr/local/texlive/2021/tlpkg/installer/wget/wget.universal-darwin --help" does not mention a --no-check-certificate option, and

	https://www.gnu.org/software/wget/manual/html_node/HTTPS-_0028SSL_002fTLS_0029-Options.html#HTTPS-_0028SSL_002fTLS_0029-Options

says, speaking ot the HTTPS options (including --no-check-certificate),

	If Wget is compiled without SSL support, none of these options are available.
