OpenSSL "ans1parse" - Configuration File for RSA Public Key
Can I build an RSA public key from an OpenSSL configuration file?
✍: FYIcenter.com
Yes, you can build an RSA public key from an OpenSSL configuration file,
if you know the components of the key, as shown in the test below:
C:\Users\fyicenter>type asn1_rsa_pub_key.cnf asn1 = SEQUENCE:rsa_pub_key [rsa_pub_key] algorithm =SEQUENCE:rsa_alg pubkey =BITWRAP,SEQUENCE:rsa_pub_components [rsa_alg] algorithm =OID:rsaEncryption parameter =NULL [rsa_pub_components] n =INTEGER:0xBB6FE79432CC6EA2D8F970675A5A87BFBE1AFF0BE63E879F2AF\ FB93644D4D2C6D000430DEC66ABF47829E74B8C5108623A1C0EE8BE217B3AD8D36D5EB4FCA1D9 e =INTEGER:0x010001 C:\Users\fyicenter>\local\openssl\openssl asn1parse -genconf asn1_rsa_pub_key.cnf -noout -out rsa_pub_key.der C:\Users\fyicenter>\local\openssl\openssl pkey -pubin -in rsa_pub_key.der -inform DER -text -noout Public-Key: (512 bit) Modulus: 00:bb:6f:e7:94:32:cc:6e:a2:d8:f9:70:67:5a:5a: 87:bf:be:1a:ff:0b:e6:3e:87:9f:2a:ff:b9:36:44: d4:d2:c6:d0:00:43:0d:ec:66:ab:f4:78:29:e7:4b: 8c:51:08:62:3a:1c:0e:e8:be:21:7b:3a:d8:d3:6d: 5e:b4:fc:a1:d9 Exponent: 65537 (0x10001)
