+.TH CRYPT_SHA512 7 "May 8, 2008"
+.SH NAME
+crypt_sha512 \- password hashing module using SHA-512 message hash algorithm
+.SH SYNOPSIS
+.LP
+.nf
+\fB/usr/lib/security/$ISA/crypt_sha512.so\fR
+.fi
+
+.SH DESCRIPTION
+.sp
+.LP
+The \fBcrypt_sha512\fR module is a one-way password hashing module for use with
+\fBcrypt\fR(3C) that uses the SHA-512 message hash algorithm. The algorithm
+identifier for \fBcrypt.conf\fR(5) and \fBpolicy.conf\fR(5) is \fB6\fR.
+.sp
+.LP
+This module is designed to make it difficult to crack passwords that use brute
+force attacks based on high speed SHA-512 implementations that use code
+inlining, unrolled loops, and table lookup.
+.sp
+.LP
+The maximum password length for \fBcrypt_sha512\fR is 255 characters.
+.sp
+.LP
+The following options can be passed to the module by means of
+\fBcrypt.conf\fR(5):
+.sp
+.ne 2
+.na
+\fB\fBrounds=\fR\fI<positive_number>\fR\fR
+.ad
+.sp .6
+.RS 4n
+Specifies the number of rounds of SHA-512 to use in generation of the salt; the
+default number of rounds is 5000. Negative values have no effect and are
+ignored. The minimum number of rounds cannot be below 1000.
+.sp
+The number of additional rounds is stored in the salt string returned by
+\fBcrypt_gensalt\fR(3C). For example:
+.sp
+.in +2
+.nf
+$6,rounds=6000$nlxmTTpz$
+.fi
+.in -2
+
+When \fBcrypt_gensalt\fR(3C) is being used to generate a new salt, if the
+number of additional rounds configured in \fBcrypt.conf\fR(5) is greater than
+that in the old salt, the value from \fBcrypt.conf\fR(5) is used instead. This
+allows for migration to stronger (but more time-consuming) salts on password
+change.
