[strongSwan] certificate format in sqlite database

[Andreas Steffen]

Hi Samuel,

in the scripts directory of the strongSwan distribution there
is a bin2sql function which converts binary DER files into a
HEX-encoded string suitable for the SQLite entry:

cat andiCert.der | ./bin2sql
X'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'
