Verifies whether the signature is valid given the message digest input. It does so by validating sig using the public key of this DSA instance.
digest is a message digest of the original input data to be signed
sig is a DSA signature value
dsa = OpenSSL::PKey::DSA.new(2048) doc = "Sign me" digest = OpenSSL::Digest::SHA1.digest(doc) sig = dsa.syssign(digest) puts dsa.sysverify(digest, sig) # => true
Performs a certificate verification on the OpenSSL::X509::Certificate cert.
chain can be an array of OpenSSL::X509::Certificate that is used to construct the certificate chain.
If a block is given, it overrides the callback set by verify_callback=.
After finishing the verification, the error information can be retrieved by error, error_string, and the resulting complete certificate chain can be retrieved by chain.
Returns true if the entry is a directory (i.e., the value of the type fact is dir, cdir, or pdir).
Returns true if files may be created in the directory by STOU, STOR, APPE, and RNTO.
Returns true if the file or directory may be renamed by RNFR.
Returns true if the RETR command may be applied to the file.
Creates a new DNS name from arg. arg can be:
Creates a new LOC::Size from arg which may be:
Creates a new LOC::Coord from arg which may be:
LOC::Coordreturns arg.
Stringarg must match the LOC::Coord::Regex constant
Creates a new LOC::Alt from arg which may be:
Returns true if there are no more events
