.... Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.
If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.
Avoid warning from groff about undefined register 'F'.

Title "SRP_VBASE_NEW 3ossl"
way too many mistakes in technical documents.
The following functions have been deprecated since OpenSSL 3.0, and can be hidden entirely by defining \s-1OPENSSL_API_COMPAT\s0 with a suitable version value, see openssl_user_macros\|(7):
.Vb 2 SRP_VBASE *SRP_VBASE_new(char *seed_key); void SRP_VBASE_free(SRP_VBASE *vb); \& int SRP_VBASE_init(SRP_VBASE *vb, char *verifier_file); \& int SRP_VBASE_add0_user(SRP_VBASE *vb, SRP_user_pwd *user_pwd); SRP_user_pwd *SRP_VBASE_get1_by_user(SRP_VBASE *vb, char *username); SRP_user_pwd *SRP_VBASE_get_by_user(SRP_VBASE *vb, char *username); .Ve
The SRP_VBASE_new() function allocates a structure to store server side \s-1SRP\s0 verifier information. If seed_key is not \s-1NULL\s0 a copy is stored and used to generate dummy parameters for users that are not found by SRP_VBASE_get1_by_user(). This allows the server to hide the fact that it doesn't have a verifier for a particular username, as described in section 2.5.1.3 'Unknown \s-1SRP\s0' of \s-1RFC 5054.\s0 The seed string should contain random \s-1NUL\s0 terminated binary data (therefore the random data should not contain \s-1NUL\s0 bytes!).
The SRP_VBASE_free() function frees up the vb structure. If vb is \s-1NULL,\s0 nothing is done.
The SRP_VBASE_init() function parses the information in a verifier file and populates the vb structure. The verifier file is a text file containing multiple entries, whose format is: flag base64(verifier) base64(salt) username gNid userinfo(optional) where the flag can be 'V' (valid) or 'R' (revoked). Note that the base64 encoding used here is non-standard so it is recommended to use openssl-srp\|(1) to generate this file.
The SRP_VBASE_add0_user() function adds the user_pwd verifier information to the vb structure. See SRP_user_pwd_new\|(3) to create and populate this record. The library takes ownership of user_pwd, it should not be freed by the caller.
The SRP_VBASE_get1_by_user() function returns the password info for the user whose username matches username. It replaces the deprecated \fBSRP_VBASE_get_by_user(). If no matching user is found but a seed_key and default gN parameters have been set, dummy authentication information is generated from the seed_key, allowing the server to hide the fact that it doesn't have a verifier for a particular username. When using \s-1SRP\s0 as a \s-1TLS\s0 authentication mechanism, this will cause the handshake to proceed normally but the first client will be rejected with a \*(L"bad_record_mac\*(R" alert, as if the password was incorrect. If no matching user is found and the seed_key is not set, \s-1NULL\s0 is returned. Ownership of the returned pointer is released to the caller, it must be freed with SRP_user_pwd_free().
\fBSRP_VBASE_add0_user() returns 1 on success and 0 on failure.
All other functions were added in OpenSSL 1.0.1.
All of these functions were deprecated in OpenSSL 3.0.
