Subject: A few fixes in the EVP_KDF-KB and EVP_KDF-KRB5KDF manpages
X-Git-Tag: openssl-3.0.0-alpha1~946
X-Git-Url: https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff_plain;h=a90311fead3d8e5178637f2d284fad95a47c281c

A few fixes in the EVP_KDF-KB and EVP_KDF-KRB5KDF manpages

The context and label is info and salt respectively - fix
the example in KB manpage for that.

There are some typos and bug in EVP_KDF_derive call in the
KRB5KDF example.
