![]() ![]() It can be set by doing RSA::setExponent(37) or whatever (37 is what puttygen uses for the RSA keys it creates). Alternate key lengths can be specified by doing RSA::createKey(1024) or whatever. Keys can be created thusly: use phpseclib3\ Crypt\ RSA īy default keys are 2048 bits. $key->getLoadedFormat() would return Raw. The key that was output would be a PKCS8 key. At that point you could load the key thusly: use phpseclib3\ Crypt\ PublicKeyLoader Let's further say that they were hex-encoded. Let's say you had the public key exponent and the public key modulo as distinct string values. These are the only formats that support multi-prime RSA. ones that don't have a red asterisk * next to them) can be found in Common Key Formats. Public keys correspond to the format described in Public Key BLOBsĪ more in-depth discussion of the common formats (ie.Private keys correspond to the format described in Private Key BLOBs.Private keys start with -BEGIN OPENSSH PRIVATE KEY.Public keys start off with - BEGIN SSH2 PUBLIC KEY.Similar to PKCS8 but with RSASSA-PSS-params for the optional "parameters" attribute and a different OID ( id-RSASSA-PSS vs rsaEncryption).Corresponds to the openssl genpkey -algorithm rsa-pss command.Keys start with -BEGIN PRIVATE KEY- or -BEGIN ENCRYPTED PRIVATE KEY- or -BEGIN PUBLIC KEY.Keys start with -BEGIN RSA PRIVATE KEY- or -BEGIN RSA PUBLIC KEY.Loading and saving keys is discussed in Public Keys: Overview. ![]()
