From aeefd5b3e2766cf2adf46ab0d391c6290c566150 Mon Sep 17 00:00:00 2001 From: markm Date: Tue, 14 May 2002 16:06:50 +0000 Subject: As the perl-generated assembler files have been committed, add the perl-generated (.pod) manual pages too. This is another nail in the perl5 coffin (for base perl, not the port or the language in general). --- secure/lib/libcrypto/man/EVP_OpenInit.3 | 198 ++++++++++++++++++++++++++++++++ 1 file changed, 198 insertions(+) create mode 100644 secure/lib/libcrypto/man/EVP_OpenInit.3 (limited to 'secure/lib/libcrypto/man/EVP_OpenInit.3') diff --git a/secure/lib/libcrypto/man/EVP_OpenInit.3 b/secure/lib/libcrypto/man/EVP_OpenInit.3 new file mode 100644 index 0000000..1309dc9 --- /dev/null +++ b/secure/lib/libcrypto/man/EVP_OpenInit.3 @@ -0,0 +1,198 @@ +.\" Automatically generated by Pod::Man version 1.15 +.\" Thu May 9 13:17:52 2002 +.\" +.\" Standard preamble: +.\" ====================================================================== +.de Sh \" Subsection heading +.br +.if t .Sp +.ne 5 +.PP +\fB\\$1\fR +.PP +.. +.de Sp \" Vertical space (when we can't use .PP) +.if t .sp .5v +.if n .sp +.. +.de Ip \" List item +.br +.ie \\n(.$>=3 .ne \\$3 +.el .ne 3 +.IP "\\$1" \\$2 +.. +.de Vb \" Begin verbatim text +.ft CW +.nf +.ne \\$1 +.. +.de Ve \" End verbatim text +.ft R + +.fi +.. +.\" 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. | will give a +.\" real vertical bar. \*(C+ will give a nicer C++.

The first call should have \fBpriv\fR set to \s-1NULL\s0 +and (after setting any cipher parameters) it should be called again +with \fBtype\fR set to \s-1NULL\s0. +.PP +If the cipher passed in the \fBtype\fR parameter is a variable length +cipher then the key length will be set to the value of the recovered +key length. If the cipher is a fixed length cipher then the recovered +key length must match the fixed cipher length. +.SH "RETURN VALUES" +.IX Header "RETURN VALUES" +\&\fIEVP_OpenInit()\fR returns 0 on error or a non zero integer (actually the +recovered secret key size) if successful. +.PP +\&\fIEVP_OpenUpdate()\fR returns 1 for success or 0 for failure. +.PP +\&\fIEVP_OpenFinal()\fR returns 0 if the decrypt failed or 1 for success. +.SH "SEE ALSO" +.IX Header "SEE ALSO" +evp(3), rand(3), +EVP_EncryptInit(3), +EVP_SealInit(3) +.SH "HISTORY" +.IX Header "HISTORY" -- cgit v1.1
