NAME

sshpk-verify - verify a signature on data using an SSH key 

SYNOPSYS

sshpk-verify -i KEYPATH -s SIGNATURE [OPTION...] 

DESCRIPTION

Takes in arbitrary bytes and a Base64-encoded signature, and verifies that thesignature was produced by the private half of the given SSH public key. 

EXAMPLES

$ printf 'foo' | sshpk-verify -i ~/.ssh/id_ecdsa -s MEUCIQCYp...OK$ printf 'foo' | sshpk-verify -i ~/.ssh/id_ecdsa -s GARBAGE...NOT OK
 

EXIT STATUS

0
Signature validates and matches the key.
1
Signature is parseable and the correct length but does not match the key orotherwise is invalid.
2
The signature or key could not be parsed.
3
Invalid commandline options were supplied.
 

OPTIONS

-v, --verbose
Print extra information about the key and signature to stderr when verifying.
-i KEY, --identity=KEY
Select the key to be used for verification. KEY must be a relative orabsolute filesystem path to the key file. Any format supported by the sshpklibrary is supported, including OpenSSH formats and standard PEM PKCS.
-s BASE64, --signature=BASE64
Supplies the base64-encoded signature to be verified.
-f PATH, --file=PATH
Input file to verify instead of stdin.
-H HASH, --hash=HASH
Set the hash algorithm to be used for signing. This should be one of sha1,sha256 or sha512. Some key types may place restrictions on which hashalgorithms may be used (e.g. ED25519 keys can only use SHA-512).
-t FORMAT, --format=FORMAT
Choose the signature format to use, from asn1, ssh or raw (only forED25519 signatures). The asn1 format is the default, as it is the formatused with TLS and typically the standard in most non-SSH libraries (e.g.OpenSSL). The ssh format is used in the SSH protocol and by the ssh-agent.
